Cuttlefish change color and pattern (including the polarization of the reflected light waves), and the shape of the skin to communicate to other cuttlefish, to camouflage themselves, and as a deimatic display to warn off potential predators. Under some circumstances, cuttlefish can be trained to change color in response to stimuli, thereby ...
The cuttlebone of a cuttlefish. This is the largest hard part of a cuttlefish, maintaining the rigidity of its body.. The common cuttlefish is one of the largest species of cuttlefish with a mantle length reaching up to 45 cm and a mass of 4 kg on a presumed male, although this is for an exceptional specimen in temperate waters; specimens in subtropical waters rarely surpass a mantle length of ...
The giant cuttlefish (Sepia apama), also known as the Australian giant cuttlefish, [3] is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and up to 100 cm (39 in) in total length (total length meaning the whole length of the body including outstretched tentacles). They can weigh over 10.5 kg (23 lb).
The pharaoh cuttlefish (Acanthosepion pharaonis) is a large cuttlefish species, growing to 42 cm in mantle length and 5 kg in weight. [2] [3]Acanthosepion pharaonis is likely a complex of at least three species, Acanthosepion pharaonis I, commonly located in the Red Sea and Persian Gulf, A. pharaonis II, located from Japan to the Gulf of Thailand and northern Australia; and A. pharaonis III ...
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.
Dwarf cuttlefish are mostly solitary in the wild, though some social behaviors have been observed. Dwarf cuttlefish will often produce patterns specific to social interactions with conspecifics. While some of these patterns have been associated with specific behaviors, e.g. aggression, it is unclear exactly how the majority of social patterns ...

The giant cuttlefish, Sepia apama, mentioned above in the section “sneaky copulations”, is born with the capacity to choose whether to change its morphology to look like a female or a mature male. When no competition is seen nearby, the cuttlefish will look like a mature male and mate with the female.
