Oct 31, 13 Comments Off on HAPPY HALLOWEEN from Curacao! Scary Face
Happy Halloween all, I have a special creation for you all today and will let you figure out what is?? A hint, it’s something from the sea!
Halloween’s roots can be traced back to Celtic culture in Ireland. According to their “Druid” religion, November 1st was New Years’ on their calendar. The celebration would begin on October 31st ,and last into the following day. The spirits of all who died in the prior year, would rise up and roam the earth on this night.
This is an evil night when spirits roamed the streets and villages. Lord Samhain, the lord of Darkness, would arrive in search of the spirits to take them to the underworld.
Halloween as it is currently celebrated with costumes, trick or treat, and superstitions, takes from this Druid Holiday.
Halloween was commonly referred to as “All Hollows” Eve. It originated from the pagan holiday honoring the dead. The Roman Catholic Church created All Saints Day (also called Hallomas) on November 1st to honor Saints and All Souls Day on November 2and to honor and pray for the souls of the dead. These holidays were created by the church, in part to downplay the pagan holidays. Needless to say, it did not succeed. Halloween as we know it today, has grown from the ancient Druid Holiday. Along the way both fun, frights, and Satanic twists have been added to the mix.
Halloween is second only to Christmas in spending. Consumers spend over $2.5 Billion during Halloween. That’s a whole lot of candy, costumes, decorations, and party goods.
Like Christmas, Halloween is steeped in traditions. While Christmas can be a stressful period, Halloween is all about fun. People really get into the Halloween tradition and “spirit”. Some religions are against celebrating Halloween, citing it’s roots in ancient Druid religion. While this is true, Today’s Halloween celebrations are all about fun, with a generous amount of imagination.
Pumpkins have inhabited the planet for thousands of years. They originated in Central America. They were used then (and now) as a food crop. Over the course of centuries, pumpkins spread their vines across all of North and South America. When Europeans arrived in the New World, they found pumpkins plentiful and used in cooking by Native Americans. They took seeds back to Europe where they quickly became popular.
Did you Know? There are no words in the dictionary that rhyme with orange? Hard to believe for such an important color? The same is true for the colors purple and silver. But, who cares about silver and purple…they are not pumpkin colors!
Growing big pumpkins is a big time hobby. And, serious at that. Top prize money for the biggest giant pumpkin is as much as $25,000 dollars at fall festivals. The current world record for giant pumpkins is 1446 pounds. Now that’s a lot of pumpkin pies!
Carving pumpkins is a traditional and fun part of Halloween. You can carve simple designs or intricate patterns. More on CarvingThe Irish carved Turnips and put coals or small candles inside. They were placed outside their homes on All Hallow’s Eve to ward off evil spirits. They were also known to use potatoes and Rutabagas.
When Irish Immigrants came to America, they quickly discovered that Jack O’Lanterns were much easier to carve out and began using them. This truly neat tradition quickly spread to the general population in America and elsewhere.
Others believe that the first Jack O’Lanterns came from the Story of Stingy Jack.

Oct 30, 13 Comments Off on Juvenile Slender Filefish, Hidden Fish, Filefish
Good morning friends, how is your week treating you??? Make sure to tune in tomorrow as I have a special Halloween photo for you and I want you to guess what it is?? Sounds fun right??
Not a whole lot to report on the Smithsonian so far this week, they had two days of problems with collecting equipment on the outside of the sub and were unable to collect specimens but I’m sure today will be different!
I came across this tiny, half inch Slender Filefish the other day hiding alongside a big sea-fan and honestly I could hardly see him! In fact I’m not even sure how I spotted him to begin with because these fish are masters at changing their colors to match almost any background in the sea. Without the use of my artificial light (flash) he is almost invisible to the naked eye and these fish don’t move around, they just hang there and become part of their surroundings, it’s really one of the most amazing things I have ever seen. They also have these sharp little spines all over their bodies that can be used as a type of anchor, by this I mean if they lean into something like the sea-fan you see here those little spines help to hold them in one place making them even harder to see because there is no movement! The filefish gets it’s name from that spine on top of it’s head that can be raised and lowered depending on the danger level, here you see it is raised. If another fish tries to eat this guy the spine on his head will be raised making trying to swallow him a very difficult or deadly situation, they are not going down without a fight.
I had a great ride with Stijn and one of his team-mates last night, we basically did an hour and a half sprint on every trail we could find and some we rode more than once, it was super hot but major fun!
Have a great day, Barry
Oct 29, 13 Comments Off on Curacao Flamingo’s, Flamingo Viewing Areas
Hey gang, I always get questions about the flamingo’s that we have here on Curacao and where they can be found. This is one of the areas at Willibrordus which is near the famous Landhuis, (landhouse) Jan Kok for which this flamingo area is named. The easiest way to find this place is to grab a map and head towards Porto Mari beach area which is located mid ways on the South side of the island. The sign and the viewing area you see above is fairly new and was much needed. If you go early in the morning you find the largest group of flamingo’s here, later in the day as you see here they are spread out everywhere and usually very far from people and their cameras. This area called St. Marie Bay where the flamingo’s now call home used to be home to about 100 slaves which mined salt in the 1860’s. Salt mining on the ABC islands was the main natural resource for hundreds of years, in 1910 16, 000 barrels were produced from these very salt ponds you see above!. The slave-built stone walls used to control salt production are still visible. I highly advise you to not go off the beaten path here, the area is filled with black-smelly quicksand or mud and I can tell you from experience you don’t want any of that action! I walked back to the car one day without shoes and I never did get them back, they are buried in smelly muck forever!
For you artsy folks out there, you can stop in at the Jan Kok Landhuis (built in 1704) and visit one of the islands top artists named Nena Sanchez, her work is sold all over the island, here is a link to her work, http://www.jankokcuracao.com/Gallery.htm
I am having a very busy day today with the Smithsonian, will write more later.
Oct 28, 13 Comments Off on Smooth Trunkfish Feeding on Christmas Tree worms
Hello friends, how was your weekend??? First off before anything else, a few days ago, sometime last week I posted a blog on a little cactus coral and found out this weekend through a coral expert that is is not a cactus coral but is in fact a juvenile boulder brain coral instead or Colpophyllia natans, here is the link to the updated post, http://www.coralreefphotos.com/ridged-cactus-coral-mycetophyllia-lamarckiana-2/ I try my best to identify reef corals and creatures the best I can but often one thing looks like another especially in their juvenile forms so feel free to send me revisions on anything you ever see wrong.
My weekend was again just a blur and as I told you in my last blog we all had to work Saturday because of folks wanting to go down in the submersible. Saturday evening and Sunday I spent a few hours on my new mountain bike trail but it’s so hot out there this time of year that the dogs and myself could only take so much so work is slow! I did get a two hour ride in Sunday morning and fought crazy wind the whole way, talk about depressing!
Here’s something you won’t see too often. This is a large sized, Smooth Trunkfish, Lactophrys triqueter eating or trying to eat a Christmas tree worm!? Yes, they love these things but as I personally have observed “you gotta be fast”!! I watched this big trunkfish spot the worm he wanted and then he slowly and I mean slowly moved in for the kill (top photo) but if he wasn’t fast enough the worm would retract back down into it’s hole to safety. The second photo shows him giving up on attacking from the air and proceeded to just suck the worm out with his big powerful mouth loaded with suction! I can’t be 100% sure if he was successful in his wormy meal but he did have his mouth over the worms tube for over a minute so I am guessing he scored! After this worm he went on to another and another and another, I almost ran out of air watching him and had wished I had gotten that on video! Most of the time these fish can be observed hunting for crustaceans in the sand by blowing big puffs of air straight down into the sand, it’s also so fun to watch and they usually don’t care if you hover and watch.
Have a wonderful day all, the Smithsonian group is getting ready for a 4-5 hour run in the submersible in search of new finds, stay-tuned!!
Oct 26, 13 Comments Off on Close-Up Gorgonian Polyps, Soft Coral Polyps
Good morning friends, sorry again about the NO Blog yesterday but with my better half gone I have double duty around the house now. So yesterday I took the day off because today, Saturday we have two sub dives, normally we are closed on the weekends. There is a big group of Marine Biologists here on the island right now having meeting and conferences almost every night and this morning some of those folks are going down in our deep-water submersible. Yesterday I started out the day by leaving the house at 6:30 in the morning with the dogs and working on a new mountain bike trail that will take months and months to finish but at least I finally got it started! We ended up only staying out there for two hours because of how hot it gets once the sun comes out and the dogs just can’t take it!! After breakfast I raced to the Sea Aquarium and picked up Carole Baldwin (Worlds top fish expert from the Smithsonian) and took her for an hour of beach combing, and it was a blast! After that I went shopping, then at 3:30 (it was crazy hot) went for an hour and a half bike ride and at 5:15 took the dogs back out for another hour and a half walk, talk about a fast paced day!
I have two different photos from two different animals showing open polyps on a soft coral called a gorgonian. Gorgonians is the preferred name for this large group of octocorals; however, they are commonly called â€œsoft coralsâ€ because of the colonies â€œlack of hard, rigid, permanent skeletonsâ€. The common name soft coral should be used when referring to members of the family Nephtheidae, abundant in the Indo-Pacific. Gorgonians include the animal colonies known as sea rods, sea whips, sea feather plumes, sea fans and orange sea whips. The stems and branches of all gorgonians have a central skeleton or axis. The central core in the suborder Scleraxonia is composed of either tightly bound or fused calcareous spicules. A wood-like core typifies the Suborder Holaxonia. The core is surrounded by gelatinous material called the rind. Polyps (above) are embedded in the rind and extend their tentacles and bodies from surface openings called apertures. The arrangement of the polyps (in rows, alternating bands, randomly scattered, ect.) is often helpful in the identification process.
Sorry short all, I just got out of the water with some guys from NASA and now have to go back under for another photo shoot. You might see us if you tune into www.seesubmarine.com
Have a wonderful weekend, Barry
Oct 24, 13 Comments Off on Bluestriped Grunt, Haemulon sciurus, Grunts
Good afternoon all, sorry so late but it’s been a crazy day so far! My day started with a trip to the airport at 4:30 in the morning as American flights now leave here at 7:00 instead of 8:00?? My wife is on her way back to the States to see her family and meet some friends and will gone for two weeks, so it’s just me, the two hound dogs and our four little land turtles!!! Also the Smithsonian group has started to arrive again and will be spending next week in search of new fish and creatures at the 1000 foot depth using our new state of the art, five person submersible called the “Curasub”. I have spent the last few days getting my aquariums cleaned out and ready in our deep-water lab for anything new and unusual that may need to be photographed that the scientists do find, so stay tuned for who knows what!!
The Caribbean reef is beautiful these past few days with crazy visibility and what seems like a record amount of baby fish! You can tune into our private underwater camera (it’s live at 50 feet) at www.seesubmarine.com and see what I’m talking about. If you sit in front of your computer long enough you will see divers, the submersible, myself with a camera and hundreds if not thousands of fish, I’ll let you sit there and count them!
Here’s a beautiful fish that is fairly unafraid of divers and will let you get pretty close, it’s called a Blue-striped Grunt, Haemulon sciurus.
Haemulon sciurus, the Blue-striped grunt, is a subtropical species of grunt native to the western Atlantic Ocean and was described by the English naturalist George Shaw in 1803.
Its common name comes from its blue stripes and from its habit of grunting by grinding its pharyngeal teeth. The swim bladder, acting as a resonator, amplifies this sound. The blue striped grunt commonly grows to a length of 20 to 25 cm (8 to 10 inches), and its maximum recorded length is 46 cm (18 inches). The maximum reported age is 12 years. It can weigh up to 750 grams.
The head and the body is yellow with many narrow, horizontal blue stripes. The stripe under the eye has a characteristic arch. There is one yellow dorsal fin with 12 dorsal spines and 16-17 dorsal soft rays. The anal fin is dusky yellow. It has three anal spines and nine anal soft rays. The soft dorsal and caudal fins are blackish. The scales above the lateral line are enlarged, while the scales below are oblique.The blue striped grunt is found in mangroves, seagrass beds, dropoffs and coral reefs at depths up to 30 meters.
The blue striped grunt is found in mangroves, seagrass beds, dropoffs and coral reefs at depths up to 30 meters. Its range includes the Western Atlantic, Florida, Gulf of Mexico, and the Caribbean down to Brazil.
The fish travels in schools with the smaller French grunt (H. flavolineatum), a close relative. Up to 1,000 grunts can form a school. The schools generally cruise near coral. Their diet consists mainly of shrimp and may also eat annelids, bivalves, and crustaceans.
Predators of the grunt are larger piscivorous fish, such as sharks.
Have a great day!! Barry
Oct 22, 13 Comments Off on Baby Bottlenose Underwater Dolphin Photos
Good morning world! This is Aimee behind the keyboard, Barry is getting ready for a mountain bike ride, and if it is a dolphin photo I love to write about it anyway! This little one is Serena. She is the baby daughter of Tela and Copan, and this photo was taken when she was only about 2 months old. Serena was born on April 19, 2012, so she is 1.5 years now.
In the past, you would have seen many photos of Tela and Pasku (her first baby, now almost 4 years old). They both participate in our open water program. With the open water program we train the dolphins to gate outside our lagoon through an underwater gate, follow a boat, and then go with us out on our nearby coral reef for exercise, research, programs and fun! Well, now Serena is being trained for the open water program as well. Unknown to most people, when dolphins see an open gate underwater, they do not just naturally and easily swim through it. So, Serena’s trainers are spending hours and hours, and now a couple of months underwater on scuba gear moving inch by inch getting Serena into our open water lagoon where she will then learn to follow the boat. Her mom Tela swims and waits patiently with another trainer in this lagoon, often going back and forth to encourage little Serena to come on out and join the fun! Once they are following the boat, we then take small steps and go a little farther each day along the reef. One of our most frequent questions is “Do they run away?” The answer is “NO!” This is home, this is where their social group is, they have food and safety. In fact if anything spooks them the first thing they do is race back to that gate! The hardest part is getting them outside.
Tela is a great and experienced mother and she will guide Serena to explore the area and most likely soon show her how to hunt the many fish on the reef. This is one of my favorite programs for both the dolphins and the people. It gives the dolphins great physical and mental exercise, is challenging and rewarding and lets us observe the dolphins out on the reef. Our dolphins are very accustomed to being around people, so they are more relaxed and will behave naturally while hunting, and diving. It is a great learning experience for us humans, and very exciting to see how well adapted they are to their ocean environment. Through the years we have photographed and video recorded many new and unusual behaviors with this open water dolphin program. So, in the future look for photos of Tela and Serena out on our reef! Enjoy and have a great day.
Oct 21, 13 Comments Off on Spanish Hogfish, Bodianus rufus, Wrasse Species
Good morning friends, I have a bright yellow fish for you all today called a Spanish hogfish. This is one of the more interesting fish on the reef and I always tell divers if you have some time, follow one of these guys and just watch how much trouble they can find! By this I mean they are into everything! Their favorite food is brittle stars and they will search every nook and cranny for these yummy morsels and I guarantee you it won’t be long until they find one! These fish are aggressive hunters and usually could care less about some diver that is following them around, they only have one thing on their minds ok, maybe two but it’s food first!
The Spanish hogfish (scientific name: Bodianus rufus) is a member of the wrasse family (Family Labridae) that lives on coral reefs in the Western Atlantic Ocean and the Caribbean Sea typically at depths ranging from one to 70 meters.
Spanish hogfish range from 20 to 40 centimeters in length. Their bodies are chiefly yellow, with purple on the upper body. Terminal phase (above) and initial phase individuals have similar coloration, and differ mainly in size; moreover, terminal phase individuals tend to be larger. This species is found in the Western Atlantic from southern Florida, USA to southern Brazil as well as in Bermuda, the Gulf of Mexico, and the Caribbean Sea. Spanish hogfish are omnivorous carnivores that feed on invertebrates such as brittle stars, crustaceans, mollusks, and sea urchins.
Juveniles hogfish act as cleaner-fish until they are about eight centimeters in length at which point they switch their diet to feeding on invertebrates. I often hover and watch as baby Spanish hogfish franticly swim from one parked fish to another trying to take care of them all, it’s really an amazing event to see!
Spanish hogfish are protogynous hermaphrodites that change sex from females to males when females reach 15 to 18 centimeters in length. Large terminal males defend harems. Spawning occrs in the water column during the late afternoon. After the eggs hatch, the larvae enter the pelagic stage until they are large enough to settle on the reef.
Studies at the Saba Reef, one of the richest fish assemblages in the Caribbean Basin, have indicated the chief threats to B. rufus and other reef fishes are overfishing and the residual impacts of the particular chemical dispersant used by the USA in the aftermath of the Deepwater Horizon oil spill; this chemical has high persistence and known toxicity to a gamut of marine fauna. Studies by Burke et al. suggest that concentrations of dispersant and other water pollutants are of particular concern in critical lagoon nurseries; these studies suggest that the toxicity of residual dispersant may be much more significant to reef fishes than the actual petroleum release of an underwater oil spill. The dispersant used in the Deepwater Horizon oil spill, Corexit 9500, is known to be much more toxic than the petroleum chemicals it is meant to disperse; moreover, the combined toxicity of Corexit 9500 and petroleum is more toxic to juvenile fish than either chemical set by itself.
We have three sub dives planned today so yours truly will be in his aqua office quite a bit today!!
Have a wonderful day!!!!
Oct 21, 13 Comments Off on Scaly-Tailed Mantis, Lysiosquilla scabricauda
Good morning from Curacao in the middle of what seems like nowhere??? Someone asked me this weekend how far we are from South America/Venezuela? The answer is; about 40 nautical miles! On a clear day, we can see the mountains of South America and they look so close. We always laugh when we go to Bonaire because of how short the flight is. You sit down, put your seatbelt on and in just a few minutes your already preparing for landing, I think it’s a 15 minute flight.
So how your weekend out there?? From watching the news we see winter is hitting all over but not here, everyday is groundhog day on this island and Yes, we do miss having seasons!
I have a giant Scaly-Tailed Mantis, Lysiosquilla scabricauda for your viewing pleasure today that I found last week while out with the macro lens. The top photo shows our clever shrimp hidden under the sand nestled in his hole waiting for some poor victim to pass by while the second photo shows him exposed after the sandy top collapsed in on him. The third photo shows him bringing up a large scoop of sand that had just fallen in and the fourth photo is of him repairing the hole which only took him around five minutes to re-seal the whole thing.
These mantis shrimps can reach a maximum size of 12 inches which this one here is close to. Their eyes are large, double-lobed, and on stalks, the body is cream colored with darkish bands across body. The â€˜claw arms’ have 8-11 spines. Create burrows on flat, sand bottoms off the coasts of Florida, Bahamas, and in the Caribbean
These shrimps will eat just about anything and are very aggressive hunters, their main diet consists of; fish, shrimp, crabs and soft-bodied prey.
Mantis shrimp are not actually shrimp, but are called stomatopods, after the order they belong to.
Stomatopods have hammer-like claws, called raptorial appendages, which can be used to spear or smash prey items. These appendages are incredibly fast (striking in 2 milliseconds) and very strong. This has earned the mantis shrimp the nick-name â€œthumb- splitterâ€ from divers whose hands got too close to the burrow.
They have up to 16 visual pigments, (Humans have 3-4 visual pigments.) They can also see ultra-violet light unlike some species that can only see polarized light.
I have to get going, the Smithsonian arrives Wednesday for another week of looking for new species so stay tuned for any possible new finds.
See you soon, Barry
Oct 18, 13 Comments Off on Juvenile Boulder Brain Coral, Colpophyllia natans
Good morning friends, I just got out of the water from a nice early morning dive and ended up finding all kinds of cool stuff!! My goal this morning was go back and find this small little black seahorse that I found yesterday but as hard as I looked I could not locate it. So after five minutes of searching I gave up and went onto something else. I was equipped with my 105 macro this morning and for once I had the right lens. My first find was an arrow crab hiding in a big azure vase sponge but he was too far down inside for a real sharp photo. Then after shooting him I noticed a little shrimp that was even deeper in the sponge and unreachable with the camera but it was a species I had never seen before?? I may have to go back there at night to get his photo. Then I found a giant slender filefish and I am sure it’s the largest one I had ever seen and I ended up playing with him for quite awhile, he was beautiful! On my way back I shot some close-ups of open polyps on a gorgonian and some beautiful new feather dusters. The photo above is what I found hidden deep down in the reef almost completely out of view, it’s a young or juvenile Boulder Brain Coral and it was only about 3 inches in width. My best find was a monster sized mantis shrimp who was out rebuilding the top of his sandy home which had recently caved in, I will have to send you a photo and better explain! My last encounter was a juvenile lizardfish buried in the sand and I ever so slowly laid down on the sand right in front of him and shot away, he never once moved!
Colpophyllia natans, known as boulder brain coral and large-grooved brain coral, is a species of stony coral found primarily in the Caribbean Sea and the Gulf of Mexico. It inhabits the slopes and tops of reefs, to a maximum depth of fifty metres. It is characterised by large, domed colonies, which may be up to two metres across, and by the meandering network of ridges and valleys on its surface. The ridges are usually brown with a single groove, and the valleys may be tan, green, or white and are uniform in width, typically 2 centimetres. The polyps only extend their tentacles at night. Individual colonies of Colpophyllia natans are large and usually broadly domed, with curvature typically increasing with the size, and therefore age, of the colony. They grow up to two metres in diameter and morphologically earn the epithet “boulder”. Colony shape may occasionally be flat-topped discs, particularly when younger. As a type of brain coral, the surface of the skeleton is a network of winding, curving valleys and ridges (or walls) that roughly resemble the familiar folding architecture of the mammal cerebrum.
The colour of the ridges and valleys vary among colonies, with the ridges being various shades of brown, and the valleys either whitish, green, or tan. The ridge tops are indented with a single thin groove. Ridges and valleys may be up to 2 centimetres wide, and this breadth distinguishes it from the narrower Diploria, which may otherwise be similar in appearance. The polyps only extend their tentacles at night.
The robust shape, size, and slow growth of the boulder brain coral allows it more easily to survive conditions to which smaller and more fragile corals, such as the plate-like lettuce coral (Agaricia agaricites), succumb. C. natans and the sympatric and similarly named boulder star coral (Montastraea annularis) are less likely to be smothered by algal bloom, and have also weathered reef-wrecking Hurricane Allen off the coast of Jamaica in 1980. Corals in the Caribbean are susceptible to bleaching caused by high water temperatures and solar radiation. A nine-month study conducted in 2005 compared the mortality of C. natans from bleaching to that of Porites porites, which has a finger-like morphology. Although the severity of bleaching between the two species was similar, 56% of the P. porites colonies studied died from the bleaching, compared to only 8% mortality for bleach-affected C. natans. However, bleaching induced widespread incidence of the coral syndrome White Plague Type II, resulting in bleaching-related mortality of 42% among C. natans over 9 months, nearly as high as that for P. porites.
These are Stony Corals even though in the photo the animal appears to be very soft. Stony corals, often called hard corals, are the basic building blocks of tropical coral reefs. These animals (polyps) secrete calcium carbonate to form hard cups, called corallites, that provide protection for their soft delicate bodies. In tropical waters most species grow colonially, joining their corallites to produce a substantial structure. Colonies increase in size by asexual budding of additional polyps and successive generations overgrowing one another.
I have to get moving, have a great day and a wonderful weekend!!
See ya, Barry
Oct 17, 13 Comments Off on Corky Sea Finger, Briareum asbestinum, Octocorals
Believe it or not I have a cool octocoral for you today that is actually a gorgonian, it’s called a Corky Sea Finger, Briareum asbestinum. These are one of the most overlooked and most under appreciated animals on the reef and yet are an essential part of our Caribbean coral reef system. Normally you find these colonies in one to several erect, unbranched, cylindrical rods, arising from a common encrusting base but in this case above they are growing in small low-growing clumps. When extended the large polyps give the colony a “hairy” appearance and the area around pore-like polyp apertures often swollen. Rods or the rind are violet to purple colored, occasionally with some tints of brown or tan with the polyps being greenish brown to brown or brownish gray. If you find these on the reef and gently fan your hand above the polyps they will quickly close leaving only the purple rind you see above, talk about a cool creature!!
Corky Sea Fingers are also referred to as the Sea Stalk Briareum, Deadman’s Fingers, Moss Coral, Encrusting Gorgonian, or simply Briareum. It has long, grass-like polyps which are normally extended continuously, retracted only when disturbed. Briareum asbestinum can have multiple forms including encrusting, flat or knobby crusts, or upright branches as pictured above. The polyps will vary in many color variations, size, and shape.
It is highly photosynthetic, containing the symbiotic algae zooxanthellae from which it receives most of its nutrients, but may also capture some particulate matter.
Well, I have to get ready to go diving, have a wonderful day all!!
Curacao regards, Barry
Oct 16, 13 Comments Off on Spiny Flower Coral, Mussa angulosa, Stony Corals
Good morning friends, I have something new for you all today called Spiny Flower Coral, Mussa angulosa and instead of just one single specimen I found a whole mound of these cool creatures! You would think after 10 years of diving with a camera that I would have already seen these but this is not the case. I have found single flower corals before but this is so cool to see so many growing together on a big mound in just 40 feet of water. If you look closely the colonies are formed of large fleshy polyps with rough blemished texture. Although the polyps are well separated on the tips of a branched structure, their expanded fleshy tissues press against adjacent individuals so tightly that an overall colony appears as a solid mound as you see above. The polyp’s skeleton is composed of numerous sharp spiked plates and is the source of it’s common name. Shades of gray, may have tints of green, blue and even fluorescent reddish orange or pink. These are also commonly known as “Large Flower Corals”.
During the day the polyps appear fleshy, but during the night they expand further and each is fringed by a rim of short tentacles. The tissues of this coral contain symbiotic single-celled algae called zooxanthellae. These are photosynthetic and absorb energy from the sun to create organic compounds which are used by the coral.
Mussa angulosa is a reef-building species and is aggressive, attacking other fast-growing corals that start to grow close by and threaten to overgrow it or shade it. Its cnidocytes are so powerful that no other Caribbean corals can successfully attack it. It leans away from the current as it grows and reacts adversely to increased sedimentation.
Hope all is well out there, another busy day ahead!!
Oct 15, 13 Comments Off on School of Blackbar Soldierfish, Myripristis jacobus
Good morning friends, we are gearing up for a very busy day here at Substation with three dives planned and the first one starting in an hour, so needless to say I will be under the sea a lot today!! Here’s a cool little reef scene I shot for you all yesterday on my morning dive out in front of Mambo Beach. I saw these four Blackbar Soldierfish hanging out under this beautiful coral ledge (which looked like a big open clam) from a long ways away and from experience knew that getting close enough for a photo would be tough! I was right. As I slowly swam up with my giant camera they all took off and hid around the corner and for the next 10 minutes just watched me from a distance but keeping close to their home. Then finally, one by one they swam back up and parked under their super cool hangout and let me shoot away deciding I was not a threat. These fish like many others are very used to a certain home and if you wait they will return, you just have to remain still and of course be ready for anything. The orange and red colors you see under the ledge are two different kinds of encrusting sponges and really “pop” or standout when artificial light is placed on them.
The fish that live here on the Caribbean reef can be found in so many different shapes, colors and all have completely different lifestyles. To reduce some of the competition between species, the coral reef has defined night and day shifts. At dusk, many species that feed during the day take shelter in the reef, while other species emerge from their daytime sanctuaries to begin making a living in the dark. One group that is a ubiquitous component of the night shift are the Blackbar soldierfish, Myripristis jacobus which is also a member of the family Holocentridae (which includes the soldier and squirrelfish).
Like some other fish that are active at night, most soldierfish are red (not a common chromatic scheme among coral reef fish) and have large eyes. Their large optical equipment enables them to see their food in very limited light. It has been speculated that a full moon is all that is required for soldierfish to see a larger crab larvae. The blackbar soldierfish gets its name from the dark bar present at the rear of the gill cover. The blackbar soldierfish can reach a total length of 8 inches.
Myripristis jacobus is found on both sides of the Atlantic. In the Western Atlantic, the blackbar soldierfish occurs from North Carolina all the way south to Brazil. The blackbar soldierfish is found on patch reefs in lagoon habitats, on reef faces and deeper reef slopes. The blackbar soldierfish has been reported at depths from 15 to over 150 feet. The blackbar soldierfish often hides in caves and crevices during the day, while at night they move out over the reef to feed on larger zooplankton.

I have to get moving, our first two lucky customers are here and they are ready to go down to 1000 feet, sounds fun right!!??

Good morning friends, I trust you all had a great weekend and your starting your Monday off with recharged batteries!!?? Yesterday morning I left the house (in the dark) at 6:00 and met Stijn at 6:30 for a three and a half hour ride through the wilds of Curacao. We both ended up wearing each other out with constant sprints, him killing me on the hills and straight-aways and me making up time on downhills and single-track, it was a lot of fun but super hot and major tiring! After our ride we just crashed and honestly didn’t want to do anything! We did find the energy to go for a snorkel in the ocean but after that I was done for the day!!
Here’s a little tiny Secretary Blenny, Acanthemblemaria maria that I found the other day while out on the reef with my 105 macro.
Secretary Blennies, (Acanthemblemaria maria) are small, tube-dwelling blennies (suborder Blennioidei) that are identified by their brownish to green delicate patterns and free moving eyes. Averaging at a size of around one inch in length, Secretary Blennies are difficult to spot when hidden in their burrowed homes. Although a variety of blenny species are commonly found in shallow reefs around the globe, Secretary Blennies are mostly distributed throughout the Bahamas and other regions of the Eastern Caribbean.
These blennies are most often found resting inside their tubed dwelling, usually burrowed into pieces of dead coral or reef, with their tiny heads bobbing in and out of the hole.
While the Secretary Blenny is most comfortable in the protection of its home, these fish are often seen poking their heads out of the hole a head approx. the size of a pea- and will rarely venture far unless jumping out for a bite to eat. This species is most recognizable by its sharp skeleton-shaped jaw and eyes that can move independently from each other.
Sorry so short, I have so much to do today!! I found a cool new coral on the reef here the other day that I am going to go photograph today so maybe I can show you that tomorrow.
Have a great day, Barry

Good morning from the Caribbean. Sorry about the no-blog yesterday but since it was an all out island holiday I took the day off from anything involving a computer! We started our day off yesterday with a nice 2 hour walk with the dogs along the shore of Saint Joris Bay, we collected beach treasures, the dogs collected sand! IMy find of the morning was a new piece of driftwood that will be used for our existing “driftwood Christmas tree”, the old trunk on last years tree was curved and not tall enough, this one should be perfect. If your wanting to see the tree from last year just click on “Driftwood Creations” on my home page on the right side and there you can see some of our fun stuff we have already made. It’s actually a rare morning that we go the coast and not haul something back, I mean who can resist all this free-stuff!?? After we got home and washed the dogs we took off to the Sea Aquarium and went for a nice morning dive but we really didn’t see much. I did get some shots of Aimee photographing some big sponges and might send one of those to you next week. The rest of our day was fairly quiet and you never would have guessed it was a Thursday?? Here’s a beautiful reef scene from the dive yesterday. Your looking at some of the most endangered corals on planet Earth called Elkhorn Coral, and we are lucky enough to have some beauties right in our own backyard!!
Elkhorn coral (Acropora palmata) is considered to be one of the most important reef-building corals in the Caribbean. This species is structurally complex with many large branches. The coral structure closely resembles that of elk antlers. These branches create habitats for many other reef species, such as lobsters, parrot-fish, snapper shrimps and other reef fish. Elkhorn coral colonies are incredibly fast-growing, with an average growth rate of 5 to 10 cm (2.0 to 3.9 in) per year and can eventually grow up to 3.7 m (12 ft) in diameter. The color of this coral species ranges from brown to a yellowish-brown as a result of the symbiotic zooxanthellae living inside the tissue of this coral species. Zooxanthellae are a type of algae which photosynthesize to provide the coral with nutrients. The zooxanthellae are also capable of removing waste products from the coral. Historically, the majority of elkhorn coral reproduction has occurred asexually; this occurs when a branch of the coral breaks off and attaches to the substrate, forming a new colony, known as fragmentation. The degree to which local stands reproduce by fragmentation varies across the Caribbean, but on average, 50% of colonies are the result of fragmentation rather than sexual reproduction. Sexual reproduction occurs once a year in August or September when coral colonies release millions of gametes by broadcast spawning.
As many of you know in 2004, the Center for Biological Diversity requested the National Marine Fisheries Service (NMFS) place all Elkhorn Coral (Acropora Palmata) on the Endangered Species list. In 2005, NMFS decided that Elkhorn coral qualified as an Endangered Species under the Endangered Species Act of 1973. On May 4, 2006 Elkhorn coral and Staghorncoral (Acropora Cervicornis) were officially placed on the Endangered Species List.
We have two sub dives today and I have a mountain bike ride planned for 5:00 with Stijn so times a waisting!!
See you soon, enjoy your weekend, Barry
