The Australian Giant Cuttlefish (Sepia apama) is the largest cuttlefish species in the world, with a maximum recorded size of 520 mm mantle length (ML) and 6.2 kg weight . It is endemic to Australian waters, with a distribution reported to extend across temperate southern Australia from southern Queensland to Point Cloates in Western Australia, and including northern Tasmania. Its life span is 1 year, perhaps 2 in some cases. It occurs on rocky reefs, seagrass beds and areas of mud and sand to depths of 100m. This species is famous for its unique and very large spawning aggregation that occurs every austral fall (May - July) in northern Spencer Gulf, northwest of Adelaide.
