Ibacus ciliatus is a species of slipper lobster from the north-west Pacific Ocean.
Ibacus ciliatus is a broad slipper lobster, with a carapace length of up to 80 millimetres (3.1 in), [3] and a total length up to 23 centimetres (9.1 in). [4] It is typically a uniform reddish brown in colour; the tail fan (uropods and telson) can be a browner or a yellower hue. [3] I. ciliatus is very similar to Ibacus pubescens , and can only be distinguished by the lack of pubescence (hairiness) on the carapace, and by the number of teeth along the edges of the carapace; in I. ciliatus there are typically 11 (occasionally 10 or 12), while in I. pubescens there are typically 12 (ranging from 11 to 14). [3]
The larvae of I. ciliatus are the typical phyllosoma larvae found in all slipper lobsters and spiny lobsters. The first phyllosoma is around 3 mm (0.12 in) across, with later stages, sometimes known as "giant phyllosomas", reaching up to 37.5 mm (1.48 in). [3]
Ibacus ciliatus occurs in the western Pacific Ocean from the Philippines to the Korean Peninsula and southern Japan (south of Niigata on the west coast and Tokyo Bay on the east coast). [1] It is the only species of Ibacus not known to occur around the coast of Australia. [5] Ibacus ciliatus lives on soft substrates at depths of 49–324 metres (161–1,063 ft), at temperatures of 14–24 °C (57–75 °F). [1]
Records of a fishery for I. ciliatus reach back to 1830, when Heinrich Bürger noted that it was on sale daily in the fish markets around Nagasaki. [1] It is now harvested throughout its range, although there is little data on the quantities being caught. [1] FAO fisheries statistics report captures of around 1,600 tonnes (3,500,000 lb) for most years since 2000, with an increase to 9,114 t (20,093,000 lb) for 2010. [6] Due to the limited knowledge of the species, it has been assessed as Data Deficient on the IUCN Red List. [1]
Ibacus ciliatus was first described in 1824 by Philipp Franz von Siebold in De Historiae Naturalis in Japonia statu ("On the Natural History of the State of Japan"), under the name "Scyllarus ciliatus". [2] [7] His holotype was deposited at the Rijksmuseum van Natuurlijke Historie in the Netherlands. [4] It was transferred to the genus Ibacus in 1841 by Wilhem de Haan. [3] A former subspecies of I. ciliatus, "I. ciliatus pubescens", is now accorded the rank of full species, as Ibacus pubescens . [1]
The official Japanese name for the species is utiwaebi (ウチワエビ), meaning "fan lobster". [3] In Thailand, it is known as kung kradan deng, while in the Philippines, the names pitik-pitik (Hiligaynon and Cebuano) and cupapa (Surigaonon) are used. [3] The English vernacular name preferred by the Food and Agriculture Organization (FAO) is "Japanese fan lobster". [4]
Spiny lobsters, also known as langustas, langouste, or rock lobsters, are a family (Palinuridae) of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, Ireland, South Africa, and The Bahamas, called crayfish, sea crayfish, or crawfish, terms which elsewhere are reserved for freshwater crayfish.
Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters.
Slipper lobsters are a family (Scyllaridae) of about 90 species of achelate crustaceans, in the Decapoda clade Reptantia, found in all warm oceans and seas. They are not true lobsters, but are more closely related to spiny lobsters and furry lobsters. Slipper lobsters are instantly recognisable by their enlarged antennae, which project forward from the head as wide plates. All the species of slipper lobsters are edible, and some, such as the Moreton Bay bug and the Balmain bug are of commercial importance.
Lipke Bijdeley Holthuis was a Dutch carcinologist, considered one of the "undisputed greats" of carcinology, and "the greatest carcinologist of our time".
Thenus orientalis is a species of slipper lobster from the Indian and Pacific oceans.
Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.
Metanephrops boschmai, known as the Bight lobster, Bight scampi or Boschma's scampi, is a species of lobster endemic to Western Australia.
Palinurus elephas is a commonly caught species of spiny lobster from the East Atlantic Ocean and the Mediterranean Sea. Its common names include European spiny lobster, crayfish or cray, crawfish, common spiny lobster, Mediterranean lobster and red lobster.
Scyllarus arctus is a species of slipper lobster which lives in the Mediterranean Sea and eastern Atlantic Ocean. It is uncommon in British and Irish waters, but a number of English-language vernacular names have been applied, including small European locust lobster, lesser slipper lobster and broad lobster.
Scyllarides latus, the Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.
Scyllarides is a genus of slipper lobsters.
Parribacus japonicus, the Japanese mitten lobster, is a species of slipper lobster. Though the common name for this lobster is the Japanese mitten lobster, it is locally called zōri-ebi (ゾウリエビ) – zōri denoting the Japanese sandal it resembles, and ebi meaning shrimp or lobster.
Eunephrops manningi, the banded lobster, is a species of lobster found in the West Indies. It was named in 1974 by carcinologist Lipke Holthuis after his friend and fellow carcinologist Raymond B. Manning.
Arctides is a genus of slipper lobsters, containing three species. The largest of these, A. antipodarum, has a carapace up to 100 millimetres (3.9 in) long, and is found off south-eastern Australia and parts of New Zealand. The other two species are smaller, at up to 70 millimetres (2.8 in) carapace length; A. guineensis is found in an area similar to the Bermuda Triangle; A. regalis is widely distributed in the Indo-Pacific, from the Mascarene Islands to Hawaii and Easter Island.
Arctides guineensis is a species of slipper lobster that lives in the Bermuda Triangle. It is known in Bermuda as the small Spanish lobster, a name which is also favoured by the FAO.
Scyllarides aequinoctialis is a species of slipper lobster that lives in the western Atlantic Ocean from South Carolina to São Paulo State, Brazil, including the Gulf of Mexico, Caribbean Sea and Bermuda. Its common name is Spanish slipper lobster. It grows up to 30 centimetres (12 in) long, with a carapace 12 cm (4.7 in) long. S. aequinoctialis is the type species of the genus Scyllarides, and the first species of slipper lobster to be described from the Western Atlantic.
Palinurus mauritanicus is a species of spiny lobster. It is found in deep waters in the eastern Atlantic Ocean and the western Mediterranean Sea.
Scyllarus pygmaeus is a species of slipper lobster that lives in shallow water in the Mediterranean Sea and eastern Atlantic Ocean. It grows to a length of 55 mm (2.2 in), which is too small for it to be fished for food. The juvenile form was first described in 1885, with the description of the adult following in 1888 as a result of the Challenger expedition.
Galearctus avulsus is a species of slipper lobster that lives around New Caledonia. It was described in 2011, having previously been included in Galearctus kitanovirosus. It differs from the other species of the genus Galearctus most noticeably in the shape of a groove on the sternum.
Ibacus alticrenatus is a species of slipper lobster that lives in the waters of Australia and New Zealand.
