This Broadclub Cuttlefish (Sepia latimanus) can go from camouflage tans and browns (top) to yellow with dark highlights (bottom) in less than a second.
Cuttlefish have an internal shell (called a cuttlebone), large eyes, and eight arms and two tentacles furnished with finely toothed suckers, with which they grab their prey.
Cuttlefish eat small molluscs, crabs, shrimp, fish and other cuttlefish. Various sharks and fish prey on them. They live about 1 to 2 years.
