Cuttlefish are cephalopods, a class found within the phylum Mollusca. Like other cephalopods, they have bilateral symmetry, a prominent head, and their "foot" has been modified into a number of arms and tentacles. They have internalized the shell found in most mollusks, and it is referred to as the cuttlebone. Cuttlefish have no backbone; they are invertebrates, and so, despite their misleading name, they are not true fish. Protruding from around their mouths, they have eight arms and two tentacles with which they catch their prey.
One of the most remarkable aspects of cuttlefish, though, is their advanced camouflaging abilities. Cuttlefish have very complex eyes, with W-shaped pupils that can see the polarization of light and in 3-D; they are, however, colorblind. Despite this, on natural substrates, cuttlefish can change color in mere seconds to blend in so well against their background that they are hardly visible. This camouflage is done by means of a vast number of small neuromuscular organs called chromatophores that expand and contract to change the color of the cuttlefish' skin. Even after the cuttlefish has died, the chromatophores may continue to cause color-change, in a distinctive post-mortem pattern known as Wolkenwandern, or "wandering clouds". There are also some other types of cells that add to the variety of colors cuttlefish can display. Cuttlefish's sides have been likened to a tv screen, so adept are they at changing colors quickly and smoothly, and in fact, some tv screens have been developed using a technology based on cuttlefish's color-changing abilities.
Yes. Cuttlefish are cephalopods alongside octopi, squid, and the painted nautaulis.
