Cuttlefish are closely related to squid and octopus, all members of the Cephalopod class. These Decopods have eight arms and two tentacles, which are used for capturing prey due to their greater length and mobility. One of the most fascinating and beautiful features of the cuttlefish is its ability to change colors in just a fraction of a second. Body patterns often shift between stripes and spots depending on mating and territorial behavior. They are of great interest to science because of their unique behavior, camouflage ability and polarized vision. In addition, they release a sepia ink, which has been utilized by artists for centuries.
