Most abundant and by far the largest local species of cuttlefish. The species can usually be recognised by the raised skin flaps, and it has three flat skin folds behind each eye. Mature animals are often curious to the point of aggressively approaching and confronting divers. The cuttlebone of this species is broad with a small spine and has a white-grey upper surface, in contrast to the pink of most other species.
