The Cuttlefish is an incredible creature.
They are absolutely extraordinary when it comes to camouflage. There is no other animal that can change colour and shape so much, quickly and so exactly according to the environment like them. They are extremely intelligent and can think in several stages and are very curious. Cuttlefishen has been a bit forgotten in studies, but it has begun to be more researches on them.
It changes the shape and color of the body if it needs to mask it self among seaweed or corals. It can turn white and pulse like a bright glow when it wants to paralyze/hypnotize a prey such as a crab (which is a favorite food), so they can slowly slide forward and take their prey. There can be light waves all over the body and small bright lights can shine like small churning over the body. They easily look like a spaceship or a creature from a science fiction movie.
From experience when I dive, the cuttlefish seems to like having a certain area and territory. It is happy to circle around that area and if it thinks it is a bit too intrusive, it will gladly take just a small circle away from you so that it can slowly circle back to its patch as it has designated. At one point my husband and I were lying in the sand looking at a cuttlefish and it came up and felt me on my hand and we were watching each other which was a really cool feeling. But after a while he seemed to have grown tired of me and my husband so it swam forward quickly and boxed on my hand and squirted up sand against us and backed off again, we realized that he said it was time to go. A nice tingling feeling when you get the opportunity to feel this communication with another species.
What I find extremely sad is that when the cuttlefish laid their eggs and they start to hatch, the life cycle is over for the parents and they die after they take care of and care for their eggs.
Around the body/along the sides are the undulating fins and they can move in all directions. They have a fairly flat body with an inner shell of porous lime. The shell is designed to regulate the gas and liquid that allows them to rise or sink into the water. That shell is what remains when the octopus dies and is called sepia shell and is sold in pet stores most often to caged birds. The cuttlefish has like a blowpipe on the underside of the head where it can shoot away water so it can go away at high speed. Like the octopus, it can spout ink to confuse predators. They have a tentacle in their mouth that looks a bit like the one you see in the Alien movies that it sends out and captures for an example a small fish.
They have several layers of skin. One has pigment cells with yellow, the other with brown and the third with red . The cells are controlled by muscles that make them small and are not visible to the muscles pulling out the pigment cells and they change color. The fourth layer has reflective cells that reflect green, blue, pink, and red. This means that the Cuttlefish has the full color spectrum that it needs.
The eyes are very different and beautiful andcan see very good.
