Feb 27, 15 Comments Off on Longsnout Seahorse, Hippocampus reidi
Good morning friends, I took yesterday off to finally get started on building a new home for our four, red-footed tortoises at their soon to be new home. A friend we work with recently told us her parents were looking for turtles for their newly opened bed and breakfast which is one of the most beautiful places I have seen and our turtles will be living like royalty! The new area they are getting is filled with low growing palms that they can crawl under, measures around 14 square feet, and will have all the comforts of home like caves and ponds, I can hardly wait to get them in there! Yesterday we removed load after load of gravel (using a wheel barrow) that was on top and dug down to the soil underneath, I will now bring in around 25, 50 lb bags of potting soil (mixed with leaves) and make a beautiful place for living, they are going to love it. We also have a truck load of giant stones arriving to place as a wall of sorts to keep them from going all over the property.
After the turtle event I got my bike gear ready for a three hour mountain bike ride at Saint Joris Bay. This Sunday morning I’m joining a friend in an event called Run, Bike, Run, he will do the running I will take care of the pedaling, should be real easy baring no flats!
I had a request for a seahorse photo so I dug into my seahorse folder and pulled out this beautiful, swimming Longsnout Seahorse, Hippocampus reidi.
For most visiting divers this is the Holy Grail of finds but sadly many will leave without ever seeing one. If you want to find a seahorse you have to dive slow, get lower to the reef and look at the base of all sponges and gorgonians, I promise you they are there you just have to find them. This little reef treasure can grow to about seven inches long and can be found in a multitude of rainbow colors. Males are often bright orange and the females yellow, both may be covered in brown or white spots, and may turn pink or white during courtship. They are found in coral reefs and sea grass beds and occasionally in the midwater of the Atlantic from North Carolina to Florida, and from the Caribbean down to Brazil. Males can carry broods of up to 1,000 young in their pouches, with larger males carrying even more young.
Of the thousands of longsnouts born in each brood, only one or two may live to become adults and raise broods of their own. In the past, that’s been enough to keep their populations healthy. But today, collectors take tons to dry and sell as souvenirs. The more that are taken, the fewer that are left to reproduce putting longsnout populations in danger.
As with other seahorses, when longsnout seahorses mate, the female deposits her eggs into a special pouch on the male’s belly. The pouch seals shut while he nurtures the developing eggs. Once the eggs hatch, the pouch opens and the male goes into labor giving birth to his tiny young.
We have 3 submersible runs today, i will be in the water a lot!
Later, have a great weekend!
Feb 25, 15 Comments Off on Colorful Stoplight Parrotfish, Sparisoma viride
Good morning all, gearing up for two dives with our submersible today, the first will be at 11:15 ish and the next at 1:30 ish, it’s always hard to stick to an exact time. You might get lucky and catch some of the action on our live underwater video at www.seesubmaine.com As most of you know by now my job is to meet the sub between 50 & 100 feet and photograph it’s lucky passengers before they descend into the Caribbean darkness, and remember we can take you down to an insane 1000 feet!
I have a Stoplight Parrotfish, Sparisoma viride in it’s initial phase meaning it will loose all the colors you see here and change into it’s terminal phase consisting of an emerald green body with salmon to yellow markings on the head and body. Even as babies or juveniles they look different than the photo above giving them three different color phases throughout it’s life. Of all the parrotfish species I chase around the reef with camera in hand, the Princess Parrotfish is the hands down easiest to approach (they could care less) and the Stoplights follow at a close second, but most of the others like the Blue’s, Midnight’s, Rainbows and Yellowtails are scared to death and won’t allow you to get close.
Parrotfishes are a group of about 90 species traditionally regarded as a family (Scaridae), but now often considered a subfamily (Scarinae) of the wrasses. They are found in relatively shallow tropical and subtropical oceans throughout the world, displaying their largest species richness in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and play a significant role in bioerosion. A number of parrotfish species, including the queen parrotfish (Scarus vetula), secrete a mucus cocoon, particularly at night.
Prior to going to sleep, some species extrude mucus from their mouths, forming a protective cocoon that envelops the fish, presumably hiding its scent from potential predators. This mucus envelope may also act as an early warning system, allowing the parrotfish to flee when it detects predators such as moray eels disturbing the membrane. The skin itself is covered in another mucous substance which may have antioxidant properties helpful in repairing bodily damage, or repelling parasites, in addition to providing protection from UV light. Although they are considered to be herbivores, parrotfish eat a wide variety of reef organisms, and they are not necessarily vegetarian.
Species such as the green humphead parrotfish (Bolbometopon muricatum) include coral (polyps) in their diets. Their feeding activity is important for the production and distribution of coral sands in the reef biome, and can prevent algae from choking coral. The teeth grow continuously, replacing material worn away by feeding. Their pharyngeal teeth grind up the coral and coralline algae the fish ingest during feeding. After they digest the edible portions from the rock, they excrete it as sand, helping to create small islands and the sandy beaches of the Caribbean. One parrotfish can produce 90 kg (200 lb) of sand each year. Or, very averagely (as there are so many variables i.e. size/species/location/depth etc), about 275 g per parrotfish per day. While feeding, parrotfish must be cognizant of predation by one of their main predators, the lemon shark.
Well, off to the sea, horrible visibility today due to a local beach being dredged!
Feb 24, 15 Comments Off on Stove-Pipe Sponge, Aplysina archeri, Reefs
Good morning friends, I’m headed out to renew some of my island I.D. cards today which is the equivalent to having your teeth pulled, not a fun event and thankfully we only have to do it once a year.
The bird I told you about yesterday that I found and held overnight is once again free! We kept him 24 hours in hopes he just needed to rest, could have been hit by a car and was dazed, who knows but he flew off last night like nothing was wrong? Weird stuff?
I have a beautiful coral reef scene for you all today with a cluster of stove-pipe sponges as the centerpiece.
Aplysina archeri (also known as stove-pipe sponge because of its shape) is a species of tube sponge that has long tube-like structures of cylindrical shape. Many tubes are attached to one particular part of the organism. A single tube can grow up to 5 feet high and 3 inches thick. These sponges mostly live in the Atlantic Ocean: the Caribbean, Bahamas, Florida, and Bonaire. They are filter feeders; they eat food such as plankton or suspended detritus as it passes them. Very little is known about their behavioral patterns except for their feeding ecology and reproductive biology. Tubes occur in varying colors including lavender, gray and brown. They reproduce both by asexual and sexual reproduction. When they release their sperms, the sperms float in water and eventually land somewhere where they begin to reproduce cells and grow. These sponges take hundreds of years to grow and never stop growing until they die. Snails are among their natural predators. The dense population of these sponges is going down because of toxic dumps and oil spills.
Have a wonderful day!
Feb 23, 15 Comments Off on Red Hind, Cleaner Fish, Epinephelus guttatus
Good morning from Curacao, how was your weekend out there?? We finally got a few little rain showers but to be honest it didn’t do much!! On my three hour mountain bike ride Sunday morning I was pretty shocked at how dry the island is looking, I hate the thought of another year of drought conditions!
We found yet another bird (big pigeon) in need last night over at our neighbors house, it was just sitting on the steps and not moving very much. I watched for awhile from a distance and then towards dark went to check on him again and he was still there. I calmly walked up the steps, he didn’t move so I picked him up and took him home, he seems to have a bad foot or something, will take him to the vet on Wednesday.
I have a Red Hind sea bass for you all today being cleaned by a little neon colored Sharknose goby. This is quite the situation. You have a big fish- eating sea bass allowing a tiny goby to swim all over it’s body, it’s a case of “you clean me and remove all my parasites and I won’t eat you”, sounds like a plan to me! These Red Hinds are very difficult to get close to, they are scared of their own shadows and rarely have I ever been able to get close enough for a photo. I think in this case he was pre-occupied with getting cleaned and although alarmed let me move in close enough for a photo but usually one shot is all you will get! This variety of sea bass is VERY common on our Caribbean reefs, they can reach a maximum length of about 2-feet and can be found in the 10-160 foot range.
Busy Monday on tap….
Have a great day all.
Feb 20, 15 Comments Off on Channel Clinging Crab, Mithrax spinosissimus
Good morning friends, wiped out this morning after a long evening of mountain biking in crazy heat and horrible wind, it’s like I tell visiting friends, “it’s not the trails that will kill you, it’s the weather”! I recently put together a new 20 mile loop consisting of all the trails I have built over the years. It has some really technical sections, fast downhills and rolling single-track and for sure is not for everyone.. but I love it!
Aimee called me yesterday from home saying that two big iguana’s had walked into our house and were fighting in our entry-way at the bottom of our steps, I asked, “did you get it on video or at least a photo” NO was the answer! But how cool is that?
I have a monster sized Channel Clinging Crab for you all today that we found out on the reef hunting for food late at night! Look at the size of those claws?? For the most part one can observe these guys up close and personal if your careful with your lights and remain still, we really love finding them and watching them climb all over the reef!
Most of you divers know this species by the common name Channel Clinging Crab, but it turns out that it has several other common names, including Reef Spider Crab, and Spiny Spider Crab, among others. The crab’s scientific name is Mithrax spinosissimus, and that designation stays the same, independent of the common name, which varies from place to place. This crab is a true crab’ (as opposed to, say, a hermit crab), and belongs to the Majidae family.
Majidae tend to have long slender legs just like this example above which is why the common names of many species in this family include the word spider’. Majids also tend to have little hairs or bristle-like structures on their carapaces. Bits of material like algae, sponge, and so on attach to those hairs and act as part of the crab’s camouflage.
Note that the walking legs of this species also are rather hairy, and are covered with stuff’ while the business end of the crab those impressive claws, are smooth.
Like so many reef creatures, this species forages mainly at night. During the day, they hunker in the reefs, under ledges, and in cavelets. Because of their size, they can’t wiggle into small cervices like so many smaller species can do. Still, they can be difficult to spot during the day, since their decorated carapaces blend so well with their surroundings.
These crabs inhabit a range from the sub-tropical western Atlantic to the Caribbean. They can be found in reef areas along the coasts of southern Florida, through the Bahamas and the Turks and Caicos Islands, and throughout much of the Caribbean.
We have another submersible dive at 11:00 so I need to get ready to dive.
Tomorrow I’m headed out to hopefully find a new home for our four land tortoises, will keep you posted.
Have a wonderful weekend!
Feb 19, 15 Comments Off on Spotted and Yellow Goatfish, Goatfishes
Good morning from Curacao!! I have two different species of Caribbean Goatfish for you all today. The top photo is a beautiful school of Yellow Goatfish, Mulloidichthys martinicus and the bottom photo shows a Spotted Goatfish, Pseudupeneus maculatus at night in it’s “inactive color phase”. During the day the Spotted Goatfish (seen here in reds) looks almost the same as the Yellow Goatfish at the top, both species have the crazy ability to change colors in the blink of an eye, it’s again just one of those weird things you have to see to believe!! Goatfish remind me of goats on land, they will eat just about anything and spend most of their days digging in the sand, silt and algae for food, they are not picky eaters! They use their chin barbels (long finger like projections under the mouth) to probe the sand as they search for the mollusks, worms and crustaceans that they feed on. While many goatfishes occur singly, the yellow goatfish is a school-forming species. It regularly occurs in large groups (numbering in the hundreds) during the day and will sometimes even form mixed schools with the blueline snapper (Lutjanus kasmira). At night, yellow goatfish schools break-up and solitary individuals or small groups disperse onto surrounding sand patches to feed. This species is very similar to the spotted goatfish (Pseudupeneus maculatus). The latter species has a yellow lateral stripe, a feature that is lacking in the spotted goatfish, and a longer snout. The yellow stripe of the yellow goatfish changes into an oblong dusky blotch when the fish is hunting for food. The yellow goatfish reaches a size between 6-12 inches while the spotted goatfish grows to 5-8 inches. Spotted goatfish are normally never found below 60 feet while the yellows are commonly spotted down to 200 feet, that’s quite a difference in range.
We have a submersible run in 30 minutes and I have a long mountain bike ride going on late this afternoon, busy day on tap!
Have a great day…
Feb 18, 15 Comments Off on Batwing Coral Crab, Carpilius corallinus, Crabs
Hi gang, how is winter treating you?? Here in Curacao winter means eighty degree plus days, lots of wind and very little moisture, in fact we hardly even had a rainy season and the island is already bone dry!!
Our friends from the Smithsonian have left and they will be missed! Believe it or not I only photographed one fish for them this trip as they did more research than collecting.
Here is a beautiful Batwing Coral crab, Carpilius corallinus for your viewing pleasure today. These crabs are so beautiful with their brilliant array of colors and that unmistakable bat outline on top of their shell. These crabs are classified as True Crabs with their smooth carapace in shades of orange, red or brown with white and yellow spots and markings. The legs are red with purple shading and the top of the shell has the outline of a bat with it’s wings open, thus the name. Although now that I said that, I have also heard these called, Coral Crabs, Red Coral Crabs and the Queen Crab. In all the years I have been here I have never seen a baby one of these, only the full grown adults which are around 4-6 inches wide measured by the width of just the carapace. I also normally never see these creatures any deeper than 50 feet and quite often I have seen them in just a meter of water getting in or out from a dive hiding under rocks. Crabs as you may or may not know have greatly reduced abdomens and tails, which are kept curled under their large, rounded, and often flattened carapace. Their first pair of legs have developed claws that are used for protection and for the manipulation of objects. If disturbed, these claws are raised toward the danger in a threatening manor. Using the remaining four pairs of legs, crabs can move rapidly in a sideways direction. Many species are quite small and secretive, and therefore very difficult to find.
I’m headed out diving with a friend from Sweden in a little bit so I need to get ready, have a great day!!
Feb 16, 15 Comments Off on Slender Filefish, Monacanthus tuckeri, Filefishes
Hi all, so very sorry about the no blogs for the past four days but I have been crazy busy! On thursday and friday we had sub dive after sub dive, then came Valentines, and yesterday was spent entertaining friends from the Smithsonian. Yesterday was also the last day of Carnival and today monday is an official day off giving all involved in Carnival a day of needed rest. I’ve also been out in the desert cleaning the 2006 World Cup mountain bike course for the past 2 weeks trying hard to get that mess cleaned and rideable, boy you want to talk about a big project! I did a fast two hour ride Sunday morning before I met the Smithsonian and then in the evening Aimee and I took the dogs out for a long two hour walk, it’s been go, go, go!
I have a super cool, two inch Slender Filefish, Monacanthus tuckeri for you all today that I found hiding in a swaying gorgonian. These little fish are completely amazing and a thrill to watch! This fish has the ability to change colors in the blink of an eye and honestly if you don’t see it yourself it’s hard to imagine and describe! Above you can see him or her blending in with the dark background and without my lights or flash you would be challenged to spot this animal on your own. These fish normally drift with their heads down and tails up among the gorgonian forests pecking at bits of algae or finding tiny shrimps. If they leave this dark environment and float into a lighter coral, they will usually change their colors before they reach their destination and I swear if you take your eyes off this fish for a second it is gone!!! These fish also have a cool spine at the top of their heads that can be raised or lowered and is used for it’s own protection. The fish also has hundreds of tiny bards all over it’s body enabling it to hook itself if you will to the swaying corals to help it stay in one place which works great at night during sleep.
Filefish (also known as foolfish, leatherjackets or shingles) are tropical to subtropical tetraodontiform marine fish of the diverse family Monacanthidae. Found in the Atlantic, Pacific and Indian Oceans, the filefish family contains approximately 107 species in 26 genera. Filefish are closely related to the triggerfish, pufferfish and trunkfish.
Their laterally compressed bodies and rough, sandpapery skin inspired the filefish’s common name; it is said that dried filefish skin was once used to finish wooden boats.
Appearing very much like their close relatives the triggerfish, filefish are rhomboid-shaped fish that have beautifully elaborate cryptic patterns. Deeply keeled bodies give a false impression of size when these fish are viewed facing the flanks. Filefish have soft, simple fins with comparatively small pectoral fins and truncated, fan-shaped tail fins; a slender, retractable spine crowns the head. Although there are usually two of these spines, the second spine is greatly reduced, being used only to lock the first spine in the erect position; this explains the family name Monacanthidae, from the Greek monos meaning “one” and akantha meaning “thorn”. Some species also have recurved spines on the base of the tail (caudal peduncle).
The small terminal mouths of filefish have specialized incisor teeth on the upper and lower jaw; in the upper jaw there are four teeth in the inner series and six in the outer series; in the lower jaw, there are 4-6 in an outer series only. The snout is tapered and projecting; eyes are located high on the head. Although scaled, some filefish have such small scales as to appear scaleless. Like the triggerfish, filefish have small gill openings and greatly elongated pelvic bones creating a “dewlap” of skin running between the bone’s sharply keeled termination and the belly. The pelvis is articulated with other bones of the “pelvic girdle” and is capable of moving upwards and downwards in many species to form a large dewlap (this is used to make the fish appear much deeper in the body than is actually the case). Some filefish erect the dorsal spine and pelvis simultaneously to make it more difficult for a predator to remove the fish from a cave.
The largest filefish species is the scrawled filefish (Aluterus scriptus) at up to 110 cm (43 in) in length; most species are below 60 cm (24 in) in length. There is marked sexual dimorphism in some species, with the sexes possessing different coloration, different body shapes, and the males with larger caudal spines and bristles.
Adult filefish are generally shallow water fish, inhabiting depths of no more than about 30 meters. They may be found in lagoons or associated with seaward reefs and seagrass beds; some species may also enter estuaries. Some species are closely associated with dense mats of sargassum, a particularly ubiquitous “sea weed”; these filefish, notably the planehead filefish (Stephanolepis hispidus) are also colored and patterned to match their weedy environments.
Either solitary, in pairs or small groups depending on the species, filefish are not terribly good swimmers; their small fins confine the fish to a sluggish gait. Filefish are often observed drifting head downward amongst stands of seaweed, presumably in an effort to fool both predator and prey alike. When threatened, filefish may retreat into crevices in the reef.
The feeding habits of filefish vary among the species, with some eating only algae and seagrass; others also eat small benthic invertebrates, such as tunicates, gorgonians, and hydrozoans; and some species eat corals (corallivores). It is the latter two habits which have largely precluded the introduction of filefish into the aquarium hobby.
Filefish spawn at bottom sites prepared and guarded by the males; both he and the female may guard the brood, or the male alone, depending on the species. The young filefish are pelagic; that is, they frequent open water. Sargassum provides a safe retreat for many species, both fish and weed being at the current’s mercy. Juvenile filefish are at risk from predation by tuna and dolphinfish.
Feb 11, 15 Comments Off on Caribbean Spiny Lobster, Panulirus argus
Good morning all, I once again had requests for lobster photos and found this giant Caribbean Spiny Lobster for your viewing pleasure today.
Spiny lobsters have long, cylindrical bodies covered with spines and two large spines that look like horns above the eyestalks. They are generally olive greenish or brown, but can be tan to mahogany. There is a scattering of yellowish to cream-colored spots on the carapace and larger (usually four to six) yellow to cream-colored spots on the abdomen. They have no claws (pincers). The first pair of antennae are slender, black or dark brown and biramous. The second pair of antennae are longer than the body, and covered with forward pointing spines. The bases of the second antennae are thick, can have a bluish tinge, and are likewise covered with rows of spines. The legs are usually striped longitudinally with blue and yellow and terminate in a single spine-like point. The somites of the abdomen are smooth and have a shallow furrow across the middle. Each has pairs of swimmerets on the underside that are yellow and black. The lobes of the tail are colored similarly to the swimmerets.
Panulirus argus may reach up to 60 cm (24 in) long, but typically around 20 cm (7.9 in), and is fished throughout its range. Sexual maturity in females is reached at a carapace length of 54“80 mm (2.1“3.1 in).
Like most decapods, P. argus hatches from eggs carried externally by the female for around four weeks. They begin life as a free-swimming, microscopic phyllosoma larvae. After about one year,the larvae settle in algae (Laurencia sp., Neogoniolithon sp.), in Thalassia testudinum seagrass beds or among mangrove roots. After undergoing several molts, they migrate to the coral reefs and live in holes or crevices. As they grow, they molt or shed their exoskeleton to make room for their larger bodies. As in other decapods, after molting, the new exoskeleton or shell is soft, and has to harden. During this time, the lobster is highly vulnerable to predation and as a result they are usually very retiring until the new exoskeleton hardens fully. The diet is mostly composed of mollusks, but they also consume detritus, vegetable material, and dead animals and fish they find on the bottom.
P. argus is a nocturnal species, taking to cover during the day. They serve as prey for skates, nurse sharks, octopuses, snappers and groupers. Although they generally prefer to remain near cover, at times groups of hundreds will line up and march across the floor off Florida and the Bahamas. The purpose of these migrations is not known, but they generally occur in the fall and may be in response to the onset of autumn storms.
Individuals can be found at depths of up to 100 m (330 ft) from Rio de Janeiro, Brazil to Beaufort, North Carolina, including the Caribbean Sea, the Bahamas and Bermuda, with occasional reports from West Africa. Although they range throughout the entire Gulf of Mexico, in the northern portions of the Gulf they generally are only found at depths of 33 m (108 ft) and greater due to the seasonal variation in the water temperature. Around the southern portion of the Florida peninsula and throughout the Bahamas and Caribbean, they are found in shallower water. They generally prefer habitat with some sort of cover and can be found around coral reefs, artificial reefs, sponges, bridge pilings, wooden bridge bumpers, piers, and under the prop roots of mangroves.
Have a great day all…
Feb 10, 15 Comments Off on Honeycomb Cowfish, Acanthostracion polygonia
Good morning friends, I have a pair of Honeycomb Cowfish, Acanthostracion polygonia for you all today that I photographed just moments before sunset. Every day here on the Caribbean reef around dusk many species of fish set out to find a mate and spawn before sunset, it’s by far the best time to be out with a camera. These unique looking box shaped Cowfish usually spend the day by them selves but around dusk will set out to find a mate. Once found the Male (in front) usually starts the courtship ritual by bumping into the female, swimming fast circles around her and showing off his beautiful electric colors which they can change in the blink of an eye! I have seen times when two different males are fighting for the same female and it always ends in one male being chased off not to be seen again! These fish are fairly uncommon to see on any given dive and I have never found a baby one, it’s on our top 10 hardest fish to find list! The babies are golden yellow with little red spots and are super cute! These fish can reach a maximum size of about 18 inches and can be found in 20-80 feet of water. Cowfish spend their days awkwardly swimming around sucking algae off rocks and enjoy all kinds of meaty foods including shrimp, worms, clams, various mussels, snails, tunicates, and fish, they are not picky eaters.
The Smithsonian just took off again down in the submersible and will not return for many hours. This trip seems to be more about collecting data than fish as they have not brought up much for yours truly to photograph.
Hope all is well out there…
Feb 9, 15 Comments Off on Ikelite GoPro Tray with Vega Video Lights
Good morning friends, how was the weekend??? I’m having a hard time getting back into the swing of things after being spoiled by my mom for three weeks, I know where they get the saying, “I want my mommy”!!
I spent my weekend trying to re-open parts of the 2006 World Cup mountain bike course that I built way back in 2004 and 2005. This is about a 5 mile loop that rarely has any bike traffic on it anymore, mostly because it’s to technical for most riders on the island. Getting it re-open means I have to push a broom through most of it removing layers of fallen thorns from our nasty trees and trim small trees and bushes, not the most fun job in the World. The dogs always keep guard while I’m busy, no one’s going to sneak up on me out there which makes me feel safe and sound!! I felt so tired this weekend that I never got on the bike, figured I would just get caught up on my rest.
Saturday afternoon I took our friend Emma (from Sweden) and our friend Sebastian (from Germany) to the North coast for our annual Ikelite Photo shoot. Our main focus for this venture was the GoPro set-up and their new T-Shirts and we easy killed two hours trying to get these shots. Most of you know how great Ikelite has been to me over the years and this is just small way to pay them back, by getting some shots of their gear in action. One of our hands down favorite new products is the GoPro tray and Vega video lights, it not only looks cool, it works!! Here is the link to your setup!
Have a great day all!!
Feb 6, 15 Comments Off on Caribbean Reef Squid, Sepioteuthis sepioidea, Squids
Hey guys, we have a lot of activity going on around here this morning. Our Substation crew is working like crazy to get the submersible ready to launch again for the Smithsonian for another day of deep sea exploration and research. In order to get the sub ready each day it first has to be charged. There are 40 rechargeable batteries onboard which can propel our little baby for around 8 hours or longer if they don’t use the robotic arms pumps. While the batteries are being charged the scrubbers are cleaned and changed, the inside is wiped down and cleaned, the big dome in the front is cleaned and the pads you lay on get taken out and vacuumed everyday. While this is being done another pilot is inside going over a long check-list involving lights, electronics, robotic arms and communications, it’s really a task to get this thing out everyday. We also have to get the cameras re-loaded and sealed back into their outside deep-water housings and put new batteries into the flash, the camera alone is a big deal.
I have a super cool Caribbean Reef Squid, Sepioteuthis sepioidea by request today. I found this colorful 10-inch squid over by a place called the “Tug Boat” a few years back and still recall the encounter like it was yesterday. This was a male who had just been chased off by another male because he was trying to put the moves on a married squid, it was not a pretty sight! I have photos of the other pair mating and this one here was left to go find himself another mate, it’s encounters like these when animals are so caught up in what they are doing that one can sometimes get very close!
Caribbean Reef Squid are largely piscovorous (means feeds of fish) and wait for their prey to approach them during the day. At night, they are more active hunters. Captured prey are generally a few centimeters long, depending upon the size of the squid. In feeding, fish are transported to the mouth by the arms where they are bitten behind the head and secured until eaten. These arms are lined with sharp hooks, corresponding to adapted sucker-rings. The tip of the arms have a cluster of smoother suckers, while the clubs at the ends of the longer tentacles have both connective tubercles and smooth suckers. The squid will feed on the flesh and internal organs of the fish but discard the head, tail, vertebrate column, and ribs. When out hunting, these squid will employ a number of very clever techniques. Individuals may raise their central upper arms to lure potential curious predators. Another method, presently exclusive to Caribbean Reef Squid, involves hiding their tentacles from the vision of their prey until the time to attack. At this time, tentacles are rapidly extended past the limit of the longest arms. Also, squid can bend their tentacles in a hooking v-pattern to aid in capturing smaller prey. In addition, upon approaching food a squid may twist and spiral its tentacles in hopes of confusing its prey.
During the day, they live in large and organized groups but are never close together and usually equally spaced apart. This species does not cooperatively drive its prey but may compete with one another for food at times. They remain closely bunched and will strike at prey generally one at a time then fall back into line with the group. However, they are known to exhibit cannibalistic activity. When ready to feed, they have been observed anchoring themselves, and remain very still, by the arm tips on the sea-floor bottom and wait for the appearance of its prey. The fish captured are primarily sardines, dwarf herring, false prichard, red, and hardhead silversides. Other prey include shrimp, mysids, and mollies. Food selection is of greatest important to the survival of young squid. In isolated studies, newly hatched squid were very selective in choosing prey but flourished upon large amounts of mysid crustaceans. Juveniles and adults also capture small planktonic animals (copepods) and small arthropods, something I have never seen yet as a photographer.
Off to play…
Feb 5, 15 Comments Off on Mahogany Snapper, Lutjanus mahogoni
Good morning friends, the eagle has landed! The trip was great, I got in tons of riding on some of the best trails in Tucson and met up with a bunch of old friends from my years in the fossil business. I stayed with my mom the whole time eating like a king and feasting on some of the best Mexican food in Tucson, boy am I going to miss that! I’m still disappointed in Nikon and their failure to get my camera cleaned and repaired which has been there for over three weeks, I can’t believe I returned without it!
The Smithsonian has arrived once again and will be using our mini-submersible to do research and hunt for new specimens, I will keep you posted on any new finds.
I have school of Mahogany Snappers, Lutjanus mahogoni for your viewing pleasure today that I found hanging out in a beautiful forest of swaying gorgoinans. These fish are fairly easy to approach and photograph if you move in very slow, (never directly towards them) and swim along side them or slowly past them, there is always time for a nice shot or two. These fish are silver to white with a reddish tinge and have a reddish border on their dorsal and anal fins. Also, there is often a dark spot below rear dorsal fin. Mahogany Snappers can be found drifting alone or in small groups (as you see above) over coral reefs, often in the shadows of gorgonians and coral heads in 20-60 feet of water. Their size ranges from 7-12 inches with a maximum length of about 15 inches.
Lots and lots to do today!!
Have a great day….

Hi everyone, sorry about the NO blogs for the past three weeks but I am without a camera! I brought my Nikon D-800 to the States to be cleaned and serviced and sent it in on the 11th and still have not gotten it back, talk about terrible service!! For you Nikon owners NEVER send you camera to the CA West-coast facility, you will regret it like I am now! And FYI if your thinking I should become an NPS member (Nikon Professional Service) I am, and even having and paying for this apparently means nothing, I guess we should all be using Canon’s, I have heard they have amazing service!
My time here was a blast, heading back to Curacao tomorrow. I did 2 weeks of non-stop mountain biking, 1st week with Outside Magazine and the 2nd week on my own shooting a fun video that I hope to get posted on YouTube sometime very soon. This last week I have been down at the 2015 Tucson Gem and Mineral Show seeing old friends and going crazy with shopping! For those of you who have never been to this event, you must put it on your to-do-list, it’s a total blast!
The Blog should start back up later this week, probably on Wednesday or Thursday.
Hope all is well out there, miss hearing from my regulars!
See you soon…
