Acanthacaris
''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. 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 . Acanthacaris have 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 gatro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lobster
Lobsters are a family (biology), family (Nephropidae, Synonym (taxonomy), 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Spence Bate
Charles Spence Bate, FRS (March 16, 1819 – July 29, 1889) was a British zoologist and dentist. Life He was born at Trenick House near Truro, the son of Charles Bate (1789–1872) and Harriet Spence (1788–1879). Charles adopted "Spence Bate" as his surname, perhaps to distinguish himself from his father, and used that name consistently in his publications; it was also used consistently by his contemporaries to refer to him. He practiced dentistry first at Swansea, and then at Plymouth, taking over his father's practice. He was president of the Odontology Society. He was an authority on the Crustacea, for which he was elected a fellow of the Royal Society in 1861, and a frequent correspondent of Charles Darwin, mostly concerning their shared interest in barnacles. Together with John Obadiah Westwood, he wrote "''A history of the British sessile-eyed Crustacea''" in 1868. He wrote reports on the crustaceans collected during the HMS ''Challenger'' expedition of 1872–1876. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Sharp Macleay
William Sharp Macleay or McLeay (21 July 1792 – 26 January 1865) was a British civil servant and entomologist. He was a prominent promoter of the Quinarian system of classification. After graduating, he worked for the British embassy in Paris, following his interest in natural history at the same time, publishing essays on insects and corresponding with Charles Darwin. Macleay moved to Havana, Cuba, where he was, in turn, commissioner of arbitration, commissary judge, and then judge. Retiring from this work, he emigrated to Australia, where he continued to collect insects and studied marine natural history. Early life Macleay was born in London, eldest son of Alexander Macleay, who named him for his then business partner, fellow wine merchant William Sharp. He attended Westminster School and Trinity College, Cambridge, graduating with honours in 1814. He was then appointed attaché to the British embassy at Paris, and secretary to the board for liquidating British claims on ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Junior Homonym
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants (I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoberus
''Phoberus'' is a genus of hide beetle in the subfamily Troginae. It was initially a subgenus of ''Trox'' before taxonomists reorganized it into its own genus. The genus is monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic gro ..., with all species evolved from a single common ancestor. Most beetle species in the genus live in Africa. It contains the following species: : Phoberus aculeatus (Harold, 1872) : Phoberus arcuatus (Haaf, 1953) : Phoberus braacki (Scholtz, 1980) : Phoberus brincki (Haaf, 1958) : Phoberus bulirschi (Huchet, 2020) : Phoberus caffer (Harold, 1872) : Phoberus capensis (Scholtz, 1979) : Phoberus consimilis (Haaf, 1953) : Phoberus cyrtus (Haaf, 1953) : Phoberus disjunctus (Strümpher, 2016) : Phoberus elmariae (van der Merwe & Scholtz, 2005) : Phoberus f ...

Trox
''Trox'' is a genus of hide beetle in the subfamily Troginae. Taxonomy In recent years, scientists have revamped the taxonomy of ''Trox''. The formerly massive genus, which boasted a whopping 160 species, has been cut down. Specifically, the subgenera '' Phoberus'' and '' Glyptotrox'' have been reelevated as their own separate genera, while various ''Trox'' species have been merged or otherwise combined. After taxonomic revisions, the genus ''Trox'' contains three subgenera - '' Trox (Trox)'', '' Trox (Niditrox)'', and '' Trox (Granulitrox)'' -, with the following species: Subgenus ''Trox'' *'' Trox acanthinus'' Harold, 1872 *'' Trox antiquus'' Wickham, 1909 *'' Trox cadaverinus'' Illiger, 1802 *'' Trox capillaris'' Say, 1824 *'' Trox contractus'' Robinson, 1940 *'' Trox coracinus'' Gmelin, 1788 *'' Trox cretaceus'' Nikolajev, 2007 *'' Trox floridanus'' Howden & Vaurie, 1957 *'' Trox gansuensis'' Ren, 2003 *'' Trox gemmulatus'' Horn, 1874 *'' Trox horiguchii'' Ochi & Kawahara ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Insect Systematics & Evolution
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
