Thymopides
''Thymopides'' is a genus of deep-water lobsters, comprising the two species ''Thymopides grobovi'' and ''Thymopides laurentae''. Distribution Two species are included in the genus ''Thymopides''. *''Thymopides grobovi'' is found around Heard Island and the Kerguelen Archipelago in the southern Indian Ocean at depths of . *''Thymopides laurentae'' is only known from a single hydrothermal vent on the Mid-Atlantic Ridge at a depth of (). Description ''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. Taxonomy The genus was first described by R. N. Burukovsky and B. S. Averin in 1976 under the name ''Bellator'', in a paper in the ''R ...

Lobster
Lobsters are a family (Nephropidae, synonym Homaridae) of marine crustaceans. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in coastal areas they populate. Commercially important species include two species of '' Homarus'' from the northern Atlantic Ocean and scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus '' Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the family Nephropidae. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homarinus
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 , 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''. Distribution and ecology The Cape lobster is endemic to South Africa. It occurs from Dassen Island, Western Cape in the west to Haga Haga, Eastern Cape in the east, a range of . Most of the known specimens were regurgitated by fish caught on reefs at depths of . This suggests ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homarus
''Homarus'' is a genus of lobsters, which include the common and commercially significant species ''Homarus americanus'' (the American lobster) and ''Homarus gammarus'' (the European lobster). The Cape lobster, which was formerly in this genus as ''H. capensis'', was moved in 1995 to the new genus ''Homarinus''. Description ''Homarus'' is one of three extant genera of clawed lobsters to show dimorphism between claws – a specialisation into a crushing claw and a cutting claw. The other similar genera are ''Nephrops'', which is much more slender, and has grooves along the claws and the abdomen, and ''Homarinus'', the Cape lobster from South Africa, which is even smaller, and has hairy claws. tp://ftp.fao.org/docrep/fao/009/t0411e/t0411e09.pdf Subfamily Nephropinae Dana, 1852 pp. 51–86 in Holthuis (1991). While analyses of morphology suggest a close relationship between ''Homarinus'' and ''Homarus'', molecular analyses using mitochondrial DNA reveal that they are not sist ...

Bellator (fish)
''Bellator'' is a genus of marine ray-finned fishes belonging to the family Triglidae, one of two genera belonging to the subfamily Prionotinae, the sea robins. These fishes are found in the Western Atlantic Ocean and eastern Pacific Ocean, in the waters off both North and South America. Taxonomy ''Bellator'' was first described as a genus in 1896 by the American ichthyologists David Starr Jordan and Barton Warren Evermann, with''Prionotus militaris'', which had been described earlier in 1896 by George Brown Goode and Tarleton Hoffman Bean from off Cape Catoche in Yucatán, Mexico, designated as its type species and also being its only species. The genus is one of 2 genera classified within the subfamily Prionotinae, the sea robins, in the gurnards family Triglidae. The genus name ''Bellator'' means "warrior", reflecting the specific name of the type species, which means "like a soldier", and is thought to be a reference to the elongate first two spines in the dorsal fin.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Warrior
A warrior is a person specializing in combat or warfare, especially within the context of a tribal or clan-based warrior culture society that recognizes a separate warrior aristocracies, class, or caste. History Warriors seem to have been present in the earliest pre-state societies. Scholars have argued that horse-riding Yamnaya warriors from the Pontic–Caspian steppe played a key role during the Indo-European migrations and the diffusion of Indo-European languages across Eurasia. Most of the basic weapons used by warriors appeared before the rise of most hierarchical systems. Bows and arrows, clubs, spears, swords, and other edged weapons were in widespread use. However, with the new findings of metallurgy, the aforementioned weapons had grown in effectiveness. When the first hierarchical systems evolved 5000 years ago, the gap between the rulers and the ruled had increased. Making war to extend the outreach of their territories, rulers often forced men from lower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

Replacement Name
In biological nomenclature, a ''nomen novum'' (Latin for "new name"), new replacement name (or replacement name, new substitute name, substitute name) is a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons (for example because it is a homonym: it is spelled the same as an existing, older name). It does not apply when a name is changed for taxonomic reasons (representing a change in scientific insight). It is frequently abbreviated, ''e.g.'' ''nomen nov.'', ''nom. nov.''. Zoology In zoology establishing a new replacement name is a nomenclatural act and it must be expressly proposed to substitute a previously established and available name. Often, the older name cannot be used because another animal was described earlier with exactly the same name. For example, Lindholm discovered in 1913 that a generic name ''Jelskia'' established by Bourguignat in 1877 for a European ...
