Giant Australian Cuttlefish

Sepia apama Gray, 1849

The largest of all the cuttlefish and an expert at colour change and camouflage. They can change colour in an instant, and by raising parts of their skin, they can also change shape and texture to imitate rock, sand or seaweed. These displays have various interpretations to other marine creatures and may be used for camouflage, mating or even hypnotising prey.

It can be identified by two rows of three skin flap-like papillae over each eye.
Their cuttlebones can be identified by the lack of a spine and a rough V-shaped thickening (callus) at posterior end. The outer cone is wide and flared in the adult
