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]
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]
Its Australian distribution includes waters of Queensland, New South Wales, Victoria, Tasmania, South Australia and Western Australia. [2]
The knifebone cuttlefish typically inhabits waters between 300 and 500 m deep. The species' known depth range extends from 132 to 803 m. [2]
The type specimen was collected in Twofold Bay, New South Wales and was described by William Evans Hoyle in 1885. [3]
Sepiidae is a family of cephalopods in the order Sepiida.
Metasepia pfefferi, also known as the flamboyant cuttlefish, is a species of cuttlefish occurring in tropical Indo-Pacific waters off northern Australia, southern New Guinea, as well as numerous islands of the Philippines, Indonesia and Malaysia. The flesh of this colorful cephalopod contains unique acids, making it unsuitable for consumption.
Sepia latimanus, also known as the broadclub cuttlefish, is widely distributed from the Andaman Sea, east to Fiji, and south to northern Australia. It is the most common cuttlefish species on coral reefs, living at a depth of up to 30 m.
Sepia kiensis is a species of cuttlefish native to the Indo-Pacific, specifically the Kai Islands, possibly to Timor and northern Australia. It lives at depth to 256 m. The validity of S. kiensis has been questioned.
Sepia mestus, also known as the reaper cuttlefish or red cuttlefish, is a species of cuttlefish native to the southwestern Pacific Ocean, specifically Escape Reef off Queensland to Murrays Beach off Jervis Bay. Reports of this species from China and Vietnam are now known to be misidentifications. S. mestus lives at a depth of between 0 and 22 m.
Sepia novaehollandiae is a species of cuttlefish native to the southern Indo-Pacific. Its natural range stretches from Shellharbour, New South Wales to North West Shelf in Western Australia. It lives at depths of between 15 and 348 m.
Sepia australis, the southern cuttlefish, is a species of cuttlefish which is found in the eastern South Atlantic Ocean and the western Indian Ocean off the coasts of Southern Africa, possibly extending into the waters off East Africa.
Sepia hedleyi, or Hedley's cuttlefish, is a species of cuttlefish in the family Sepiidae, endemic to subtropical and temperate waters off Australia.
Sepia saya is a species of cuttlefish known only from its type locality in the southwestern Indian Ocean. It lives at depths of 87 to 117 m.
Sepia tuberculata is a species of cuttlefish native to South African waters from Melkbosstrand to Knysna. It belongs to the genus Sepia. It lives in very shallow water to a depth of 3 m. It is endemic.
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy.
Sepia vermicularis, the patchwork cuttlefish.sometimes known as the common cuttlefish or ink-fish in South Africa, but the name common cuttlefish is more widely applied to Sepia officinalis. It is endemic to southern Africa.
Sepia zanzibarica, or the Zanzibar cuttlefish, is a species of cuttlefish native to the Indian Ocean.
Sepia trygonina, the trident cuttlefish, is a species of cuttlefish in the genus Sepia from the Red Sea and the western Indian Ocean. Cuttlefish are a specific type of cephalopod that is a highly evolved branch of the Mollusca phylum. They are characterized by having a calcareous shell that is covered by a membrane with free fin lobes that are laterally placed on both sides of their head. They have a centered beak that is used for feeding which is surrounded by 10 appendages. The trident cuttlefish are carnivores that prey on fish, crustaceans, and shellfish. They are also a major source of food for larger marine life like dolphins, seals, and even birds.
Sepia prashadi, common name hooded cuttlefish, is a widely distributed species of cuttlefish. It has a thin, oval body and grows from 5 to 11 cm. The tips of the tentacles have a distinct club shape. S. prashadi is a migratory, demersal cuttlefish living in shallow waters at depths of approximately 40 to 50 metres. It is found in many locations including the east coast of Africa, around India, in the Red Sea, and Persian Gulf.
Sepia braggi, the slender cuttlefish, is a species of cuttlefish native to the Indo-Pacific Ocean. It has been found in coastal waters of southern Australia. This species was first collected in South Australia by its namesake, William Lawrence Bragg. Sepia braggi was then described by Sir Joseph Cooke Verco in 1907.Sepia braggi is part of the subgenus Doratosepion which contains to 41 species of cuttlefish in total.
Sepia elegans, the elegant cuttlefish, is a species of cuttlefish in the family Sepiidae from the eastern Atlantic Ocean and the Mediterranean Sea. It is an important species for fisheries in some parts of the Mediterranean where its population may have suffered from overfishing.
Sepia bertheloti, the African cuttlefish, is a species of cuttlefish from the family Sepiidae which is found in the warmer waters of the eastern Atlantic Ocean off Africa.
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.
Sepia hierredda, the giant African cuttlefish, is a species of cuttlefish from the family Sepiidae, which was previously considered conspecific with the common cuttlefish Sepia officinalis. It is found along the western coast of Africa and is an important species to fisheries.
