The broadclub cuttlefish is a large, robust cephalopod found across the Indo-Pacific, typically inhabiting sandy and muddy bottoms from shallow waters down to around 60 metres. It is distinguished by its broad, flattened body and relatively short arms compared to other cuttlefish species. Like all cuttlefish, it is a master of rapid colour and texture change, using chromatophores and papillae to vanish against the seabed or signal to rivals and mates. Divers may encounter it resting on the bottom during the day, where its cryptic abilities make it easy to overlook unless movement gives it away.
