Body
There are over 100 known species of Cuttlefish on the planet. Every species has eight arms and two long tentacles. On each arm there are suckers, which help in catching prey, similar to the arms of an octopus. Their skin can change color the same way a chameleon's can in order to hide from predators. Their cuttlebone, or shell, is filled with gas which helps them stay afloat.ARKive: Common cuttlefish (Sepia officinalis)
