Sepia latimanus, also known as the broadclub cuttlefish, is widely distributed from the Andaman Sea, east to Fiji, and south to northern Australia.

It is the most common cuttlefish species on coral reefs, living at a depth of up to 30 m.[3] The type specimen of Sepia latimus was collected in New Guinea and is deposited at the Muséum National d'Histoire Naturelle in Paris.

Sepia latimanus has a wide distribution in the Indo-Pacific region from the coasts of eastern Africa in the west following the continental coastline through southern Asia to southern Japan and as far south as northern Australia and the Coral Sea.

It is diurnal species which appears to mesmerise its prey by using a display consisting of a series of rhythmic colour bands running along its body.

Their courtship is highly ritualized and stereotyped, and like their hunting behaviour it includes striking visual displays.
