Science in Seconds - Cuttlefish

0 (0 Likes / 0 Dislikes)
Science in Seconds Know Everything RAVES - Cuttlefish Torah Kachur: I often spend my Saturday nights trying to think my skin a different color. So far, no dice. The cuttlefish, however, can use neuroimpulses to change the color of its skin. They can think themselves into looking like a rock, a piece of coral, or a wicked acid trip. Cuttlefish, which aren't fish, have tiny muscles that control the expansion and contraction of chromatophores, pigment containing cells. Millions of different chromatophores are present in three layers: yellows, reds, then browns and blacks at the deepest surface, allowing the cuttlefish to create all the colors of the visible spectrum. They use their psychedelic prowess to attract mates and deter competition. This surprises me, as they shouldn't need help finding the ladies with this beautiful mug. Also, they can change their colors for camouflage. They can mimic not only the color of their surroundings, but the texture, too. They can actually control their chromatophores to look like a sandy bottom, complete with hills and ridges. With all of this control over their little muscles, these relatives of the octopus and squid have an incredibly complex nervous system, and also some of the most refined eyesight in all the animal kingdom. You think I'm making all this up, don't you? Well, see it to believe it. Courtesy of Science in Seconds – All rights reserved Only for educational/non-profit purposes.

It's not a fish. It's the most psychedelic guy in the sea.
