Sepia orbignyana, the pink cuttlefish, is a species of small cuttlefish from the family Sepiidae. It is occurs in the temperate and tropical waters of the eastern Atlantic Ocean.

Description Sepia orbignyana is a fairly small cuttlefish, growing up to 12 cm in total length. The females are generally larger than the species' males; male mantle length up to 84mm and females' up to 120mm. It has a slim, oval body and relatively long arms, each having four rows of suckers. There is an obvious lobe of the dorsal mantle which projects between the eyes and there is a prominent tip at the posterior end of the mantle, which lies in the gap between the posterior ends of the fins. The tentacular club is short and has its suckers arranged in five–six rows, with the middle series having three to four greatly enlarged suckers. The hectocotylus is found on the left ventral arm and has one or two rows of suckers of normal size at the base, highly reduced suckers in the mid part and then normal size suckers towards the tip. The suckers on the hectocotylus are arranged in two dorsal and two ventral series each of which are laterally displaced to create a gap between them. Females have a single spermathecae situated medially on the ventral part of the buccal membrane.
