Hi gang, how was your Fourth of July?? Send us some stories of what activities you all did would love to hear about it. There were no fireworks here last night, I think that’s a first but all in all it’s been fairly quiet around here, doesn’t seem to be that many tourists around lately.
I found this close-up shot of a Caribbean Squid and his beautiful colors from a night dive I did a few months ago. I remember this squid was circling around me flashing what looked like every color under the rainbow, it was such a great show and I had a front row seat! Many don’t know that squid skin is translucent. The color comes from pigment cells, called chromatophores, located in the outer layer of skin. These chromatophores appear as small patches or dots. Chromatophores in Caribbean Reef Squid contain red, yellow, blue, green, purple, orange, maroon or brownish-black pigments. Muscles controlled by nerve fibers control the chromatophores. Different nerve fibers control different colored chromatophores. This allows the squid to selectively retract or expand sets of chromatophores and to increase or decrease the amount of a selected color. By expanding the red chromatophores, as squid may do when excited, the squid will flush with a bright red color. Rapidly retracting all the chromatophores reduces all the colors and the squid appears colorless.
Not much news from Curacao for you tonight, the puppies are doing well and it’s great to have our Aimee home! I’ll be back tomorrow night, Barry
