Acanthacaris is a genus of deep-water lobsters. It contains two species, A. caeca and A. tenuimana, and is the only genus in the subfamily Neophoberinae. [1] [2] [3]

Description

They are relatively large lobsters with a cylindrical body covered with sharp spines (hence the genus name, meaning "spiny shrimp"). The carapace has a well-developed rostrum. The eyes are very small and lack pigment, while the antennae are long and whiplike. The telson and uropods are powerful. The first three pairs of walking legs end in claws. The first pair of claws is symmetrical and ends in long fingers covered with sharp spines on cutting edges but without hairs. The second pair of walking legs is much longer than the third pair. Both species reach a length of 40 centimetres (16 in). [1] Acanthacaris has a laterally compressed rostrum, a unique arrangement of postcervical and cellar grooves, a large and elongate scaphocerite, and delicate, elongate claws with cylindrical palms. The acanthacaris have no gatrolateral or postcervical spine.

Taxonomy

The genus Acanthacaris is the only genus in the subfamily Neophoberinae and contains two species:

The genus was originally described as "Phoberus" by Alphonse Milne-Edwards in 1881, with "Phoberus caecus" (A. caeca) as the type species; this transpired to be a junior homonym of Phoberus erected by William Sharp Macleay in 1819 (a subgenus of the beetle genus Trox ). [1] [4] Although the replacement name ( nomen novum ) "Neophoberus" was provided by Martin Glaessner in 1969, [5] this is pre-dated by Charles Spence Bate's 1888 name Acanthacaris, which has A. tenuimana as the type species.

<i>Homarus</i> Genus of lobsters

Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus and Homarus gammarus. The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus.

<i>Nephrops norvegicus</i> Species of lobster

Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, shlobster (shrimp-lobster), langoustine or shrimp, is a slim, coral colored lobster that grows up to 25 cm (10 in) long, and is "the most important commercial crustacean in Europe". It is now the only extant species in the genus Nephrops, after several other species were moved to the closely related genus Metanephrops. It lives in the north-eastern Atlantic Ocean, and parts of the Mediterranean Sea, but is absent from the Baltic Sea and Black Sea. Adults emerge from their burrows at night to feed on worms and fish.

<span class="mw-page-title-main">Slipper lobster</span> Family of crustaceans

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.

Astacidea is an infraorder of decapod crustaceans including lobsters, crayfish, and their close relatives.

<span class="mw-page-title-main">Cape lobster</span> Species of crustacean

The Cape lobster, Homarinus capensis, is a species of small lobster that lives off the coast of South Africa, from Dassen Island to Haga Haga. Only a few dozen specimens are known, mostly regurgitated by reef-dwelling fish. It lives in rocky reefs, and is thought to lay large eggs that have a short larval phase, or that hatch directly as a juvenile. The species grows to a total length of 10 cm (3.9 in), and resembles a small European or American lobster; it was previously included in the same genus, Homarus, although it is not very closely related to those species, and is now considered to form a separate, monotypic genus – Homarinus. Its closest relatives are the genera Thymops and Thymopides.

<i>Metanephrops challengeri</i> Species of crustacean

Metanephrops challengeri is a species of slim, pink lobster that lives around the coast of New Zealand. It is typically 13–18 cm (5–7 in) long and weighs around 100 g (3.5 oz). The carapace and abdomen are smooth, and adults are white with pink and brown markings and a conspicuous pair of long, slim claws. M. challengeri lives in burrows at depths of 140–640 m (460–2,100 ft) in a variety of sediments. Although individuals can live for up to 15 years, the species shows low fecundity, where small numbers of larvae hatch at an advanced stage.

<i>Ibacus peronii</i> Species of crustacean

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.

<i>Scyllarides latus</i> Species of crustacean

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.

<i>Lepidophthalmus turneranus</i> Species of crustacean

<i>Neoglyphea</i> Genus of crustaceans

Neoglyphea inopinata is a species of glypheoid lobster, a group thought long extinct before Neoglyphea was discovered. It is a lobster-like animal, up to around 15 centimetres (5.9 in) in length, although without claws. It is only known from 17 specimens, caught at two sites – one at the entrance to Manila Bay in the Philippines, and one in the Timor Sea, north of Australia. Due to the small number of specimens available, little is known about the species, but it appears to live up to five years, with a short larval phase. A second species, previously included in Neoglyphea, is now placed in a separate genus, Laurentaeglyphea.

Thymopides is a genus of deep-water lobsters, comprising the two species Thymopides grobovi and Thymopides laurentae.

<i>Palinurus charlestoni</i> Species of crustacean

Palinurus charlestoni is a species of spiny lobster which is endemic to the waters of Cape Verde. It grows to a total length of 50 cm (20 in) and can be distinguished from other Atlantic species in the genus by the pattern of horizontal bands on its legs. It was discovered by French fishermen in 1963, and has been the subject of small-scale fishery since. It is thought to be overexploited, and is listed as Near Threatened on the IUCN Red List.
