Thymopides is a genus of deep-water lobsters, comprising the two species Thymopides grobovi and Thymopides laurentae.
Two species are included in the genus Thymopides.
Thymopides differs from related genera such as Homarus , Homarinus and Nephrops in having the first pair of pereiopods of similar size and shape, rather than one "crusher" and one "cutter" claw. It differs from others, such as Metanephrops and Eunephrops by the lack of a carina behind the antennal spine, by the smaller size of some spines and by the smaller, unpigmented eyes.
The genus was first described by R. N. Burukovsky and B. S. Averin in 1976 under the name Bellator, in a paper in the Russian Journal of Zoology (Зоологический Журнал, Zoologicheskij Zhurnal). After Lipke Holthuis informed the authors that a genus already existed called Bellator , they published a replacement name in a paper in the journal Crustaceana . That new name was Thymopides, referring to the close resemblance between the new genus and the genus Thymops . The original genus name, Bellator derived from the Latin word bellator , meaning "warrior".
In 2003, a second species was described, T. laurentae, commemorating Michèle de Saint Laurent.
Lobsters are a family of large marine crustaceans.
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.
Nephrops is a genus of lobsters comprising a single extant species, Nephrops norvegicus, and several fossil species. It was erected by William Elford Leach in 1814, to accommodate N. norvegicus alone, which had previously been placed in genera such as Cancer, Astacus or Homarus. Nephrops means "kidney eye" and refers to the shape of the animal's compound eye.
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.
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.
Mirocaris is a genus of shrimp associated with hydrothermal vents. Sometimes considered the only genus of the family Mirocarididae, Mirocaris is usually placed in the family Alvinocarididae. The genus contains two species, M. fortunata and M. indica; the former species M. keldyshi is now considered synonymous with M. fortunata. The two species are found in different oceans, and can be distinguished by the pattern of setation on the claw of the first pereiopod.
The family Thaumastochelidae contains five known species of deep-sea lobsters, three in the genus Thaumastocheles, and two in the genus Thaumastochelopsis. The fifth species was discovered in the ten–year Census of Marine Life. These creatures are distinguished from other clawed lobsters by their blindness, and by their single elongated, spiny chela.
Metanephrops is a genus of lobsters, commonly known as scampi. Important species for fishery include Metanephrops australiensis and Metanephrops challengeri. It differs from other lobsters such as Homarus and Nephrops norvegicus in that its two main claws are of equal size, rather than being differentiated into a crusher and a pincher. There are 18 extant species recognised in the genus:
Justitia is a genus of spiny lobsters. Following the recognition of Nupalirus as a separate genus, Justitia comprises one extant species and two fossil species:
Munidopsis serricornis is a species of squat lobster. It is widely distributed in the world's oceans, being found in the eastern Atlantic Ocean, the western Atlantic Ocean, and the Indo-Pacific. It grows up to a carapace length of 20 millimetres (0.8 in).
Scyllarides is a genus of slipper lobsters.
Dinochelus ausubeli is a small deep sea lobster discovered in 2007 in the Philippines during the Census of Marine Life and described in 2010 in the new genus Dinochelus. Its two claws are very different in size, are elongated, and bear many long teeth on the inner surface.
Galearctus is a genus of slipper lobsters, comprising the following species:
Nephropides caribaeus is a species of lobster, the only species in the genus Nephropides. It is found in western parts of the Caribbean Sea, from Belize to Colombia. It grows to a total length of around 170 mm (6.7 in), and is covered in conspicuous tubercles.
Munidopsis tuberosa is a species of squat lobster, first isolated from deep waters off Taiwan. M. tuberosa is similar to M. granosicorium, but it differs by the configuration of its carapace and rostrum.
Munidopsis echinata is a species of squat lobster, first found in deep waters off Taiwan. M. echinata is similar to M. colombiana, but differs by lacking an antennal spine on its carapace and having a rather longer antennal peduncle.
Eumunida chani is a species of chirostylid squat lobster first found in Taiwan. This species can be distinguished by its absence of a pad of densely distributed setae on its first pereopod, the anterior branchial margin which bears two spines, and the carpus of its first pereopod carrying only two spines.
Uroptychus singularis is a species of chirostylid squat lobster first found in Taiwan. This species is distinguished from U. australis by its single, unpaired terminal spine on its flexor margin of pereopods 2–4.
Munidopsis tafrii is a species of squat lobster first found in Taiwanese waters at depths greater than 3,000 metres (9,800 ft). It resembles M. ceratophthalma, however its carapace morphology distinguishes it from its cogenerate species.
Raymunida dextralis is a species of squat lobster in the family Munididae from the Pacific and Indian oceans. The species can be distinguished by its morphological characters and its mitochondrial cytochrome c oxidase subunit I sequences.
