Broadclub cuttlefish are usually found free swimming in reef areas. They are active during the day and can often be seen hunting for fish and crustaceans. They are the most common species of cuttlefish on coral reefs. They are capable of rapid color change, usually into a spotted white and brown pattern, and their large eyes have a bright yellow rim. Their common name is derived from the broad club-like feeding arms. Can grow up to 10kg in weight. Second largest Sepia cuttlefish species.
