Cuttlefish

Cuttlefish are relatives of squid and octopuses whose broad bodies are supported by an internal cuttlebone. Rippling fins allow controlled movement, while jet propulsion can provide a faster escape. Feeding tentacles extend to seize prey and draw it toward the arms. Skin pattern and texture can change during camouflage or social interactions. Species vary in size and habitat, but the combination of a cuttlebone and specialized feeding tentacles distinguishes the group.
