Sepia zanzibarica | |
Sepia zanzibarica, or the Zanzibar cuttlefish, is a species of cuttlefish native to the Indian Ocean.
The arms of Sepia zanzibarica have four series of suckers with a hectocotylus present on the left ventral arm which has 6 rows of suckers which are highly reduced in size in the middle and normal sized towards the tip of the arm with the oral surface of modified region is wide, engorged, fleshyand has transversely grooved ridges. The suckers of two each of the dorsal and ventral series are laterally displaced and widely separated while another 2 ventral serues are so close that the sucker rows appear to alternate. The tentacular clubs are short and oval with six suckers in crosswise rows, the suckers vary in size with some on the inner rows being a little largers than the others The swimming keel of the club reaches slightly beyond the carpus at the end nearest the head and the ventral protective membranes do not join at the club base. There are a small number of tiny suckers on the buccal membrane. The cuttlebone is oblong in shape, rounded on the anterior and posterior edges, a strongly recurved ventral surface and an evenly convex dorsal surface. [3] The mantle length averages 250 mm. [1]
It is found in the western Indian Ocean along the east coats of Africa from Port Elizabeth in the Eastern Cape Province of South Africa north to Djibouti and the Gulf of Aden, it is also found off Madagascar, the Comoro Islands and the Mascarene Islands, as well as the Seychelles and Socotra. [1]
Sepia zanzibarica occurs at depths of 34 to 95 m. [3]
Sepia zanzibarica is a commercially important quarry for fisheries in the Gulf of Aden and it is probably an important part of the mixed species fisheries along costa of eastern African and in deeper waters. [3]
The paintpot cuttlefish is a small, poorly researched species of cuttlefish found in the Indo-Pacific, between Japan and Hong Kong. It is one of the two species classified in the genus Metasepia. Metasepia cuttlefish are characterized by their small, thick, diamond-shaped cuttlebone, and distinctive body coloration.
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.
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.
The pharaoh cuttlefish is a large cuttlefish species, growing to 42 cm in mantle length and 5 kg in weight.
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 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.
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 trygonina, the trident cuttlefish, is a species of cuttlefish in the genus Sepia from the Red Sea and the western Indian Ocean. 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.
Enoploteuthis leptura, the hooked enope squid, is a species of squid from the family Enoploteuthidae. It is the type species of the genus Enoploteuthis, which is in turn the type genus of the Enoploteuthidae.
Ornithoteuthis volatilis, the shiny bird squid, is a squid from the subfamily Ommastrephinae, the flying squids, of the family Ommastrephidae part of the pelagic squid order Oegopsida. It is a tropical and sub-tropical species which is widely distributed in the Indo-Pacific oceans. It is slightly larger than the closely related species Ornithoteuthis antillarum of the Atlantic Ocean.
The Angolan flying squid is a species of squid from the subfamily Todarodinae, part of the family Ommastrephidae. Due to taxonomic confusion with the Antarctic flying squid the exact limits of its distribution are uncertain but it is thought to be restricted to waters off Southern Africa.
Sepia lycidas, commonly known as the kisslip cuttlefish, is a species of cuttlefish within the genus Sepia. They are also classified under the family Sepiidae, which encompasses some of the most commonly known and recognized cuttlefish. Phylogenetically, this species of cuttlefish is most closely related to Sepia aculeata, Sepia esculenta, and Sepia pharaonis. This species is typically reddish brown to purple in color, with patches and stripes present on their dorsal mantle. On average, they grow to be about 38 cm in length and weigh 5 kg at maximum. The kisslip cuttlefish can be found mainly within the Indo-West Pacific, at depths ranging from 15–100 meters. Additionally, this species exhibits many diverse, complex reproductive behaviors; for example, courting, mating displays, and mate competition. Other interesting behaviors includes their feeding and hunting methods, which entails turning towards a preferred direction to "jump on" and engulf their prey of small fish and crustaceans. Sepia lycidas has many human uses and is important in the economy of many Southeast Asian countries, especially since they are often eaten for their high nutritional value. They are also currently being studied as an alternative source of collagen for human use, since their thick outer skin contain high levels of collagen that goes to waste when they are eaten or caught as bycatch.
