Sepia cultrata, commonly known as the knifebone cuttlefish or elongated cuttlefish, is a species of cuttlefish from the family Sepiidae endemic to the southern Indo-Pacific. It is a deepwater species found in subtropical and temperate Australian waters. [2]

Description

Sepia cultrata has a pale buff pinkish brown colour. It has a crescent-shaped club with a flattened sucker bearing 5 or 6 small suckers in transverse rows. The cuttlebone is an elongate oval shape with triangular pointed anterior and narrow posterior ends. It has a salmon-coloured dorsal surface with ribbing: the median rib is distinct and narrow, flanked by two faint lateral ribs. Its mantle grows to a maximum size of 12 cm. [2]

Distribution

Its Australian distribution includes waters of Queensland, New South Wales, Victoria, Tasmania, South Australia and Western Australia. [2]

Habitat and ecology

The knifebone cuttlefish typically inhabits waters between 300 and 500 m deep. The species' known depth range extends from 132 to 803 m. [2]

Naming

The type specimen was collected in Twofold Bay, New South Wales and was described by William Evans Hoyle in 1885. [3]

The giant cuttlefish, also known as the Australian giant cuttlefish, is the world's largest cuttlefish species, growing to 50 cm (20 in) in mantle length and up to 100 cm (39 in) in total length. They can be over 10.5 kg (23 lb) in weight. Like all cuttlefish species, the giant cuttlefish has 8 arms and 2 feeding tentacles, as well as blue blood and 3 hearts. Using cells known as chromatophores, the cuttlefish can put on spectacular displays, changing colour in an instant. The giant cuttlefish is native to temperate and subtropical waters of Australia, from Brisbane in Queensland to Shark Bay in Western Australia and Tasmania to the south. It occurs on rocky reefs, seagrass beds, and sand and mud seafloor to a depth of 100 m (330 ft). In 2009 the species was listed at Near Threatened on the IUCN Red List of Threatened Species due to an observed declining trend at that time.
