Hyas Coarctatus
''Hyas coarctatus'' is a marine crab species native to the North Atlantic. It is characterized by a lyriformed shell. Morphology ''Hyas coarctatus'' looks like the great spider crab (''H. araneus'') but has a lyriformed shell. The carapace of a large specimen is up to 60 mm long and 44 mm wide. The colour is grey-brown on the dorsal side, sometimes with a bit reddish, the ventral side is dirty white. The rostral horns of ''H. coarctatus'' are slightly longer and spaced further apart than in ''H. araneus''. Chelipeds are longer than in ''H. araneus''. The outer segment of the walking legs is often more or less furry. Distribution and ecology ''H. coarctatus'' is found at both hard, stony, sandy and soft bottoms from 1 to 500 meters depth, though most often above 50 meters. ''H. araneus'' inhabits shallower depths. ''H. coarctatus'' is widely distributed in the North-East Atlantic and adjacent seas. The northern border is around the north and west coasts of Spitsbergen and Ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Elford Leach
William Elford Leach Royal Society, FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Royal Devon and Exeter Hospital, Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating Doctor of Medicine, MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Museum, London, Natural History Department of the British Museum, where he had responsibility for the zoological ...

Hyas Araneus
The great spider crab, ''Hyas araneus'', is a species of crab found in northeast Atlantic waters and the North Sea, usually below the tidal zone. In 1986, two specimens were captured at the South Shetland Islands off the Antarctic Peninsula The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctic ..., apparently transported by human agency. It has been feared that the species would have an adverse effect on the native fauna, but there have been no further captures from the region since the 1986 specimens. The great spider crab can moult and get rid of their outer shell/skin. This can take some time but it lets them grow to great size. After they moult they are very vulnerable to predators because of a very soft exoskeleton. References Majoidea Crabs of the Atlantic Ocean Crustacean ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raffles Bulletin Of Zoology
''The Raffles Bulletin of Zoology'' is a peer-reviewed open-access scientific journal published by the Lee Kong Chian Natural History Museum at the National University of Singapore. It covers the taxonomy, ecology, and conservation of Southeast Asian fauna.Supplements are published as and when funding permits and may cover topics that extend beyond the normal scope of the journal depending on the targets of the funding agency.

Hyas Alutaceus
Hyas ( grc, Ὑάς, Hūás, ; ), in Greek mythology, was a Boeotian who was regarded as the ancestor of the ancient Hyantes (Boeotians). His name means rain from ''hyô, hyetos.'' Family Hyas was the son of the Titan Atlas and either of the Oceanids, Pleione or Aethra, thus brother to the Pleiades and Hyades.Hesiod, ''Astronomy'' fr. 2 from Scholiast on Aratus, 254; Hyginus, ''Fabulae'192 ''De Astronomica'2.21.4/ref> In one account, Hyas instead was called the father of the Hyades by Boeotia. Mythology Death Hyas was a notable archer who was killed by his intended prey. Some stories have him dying after attempting to rob a lion of its cubs. ''While his .e. Hyasbeard was fresh, stags trembled in terror before him, and the hare was welcome prey. But when years matured his manhood, he breavely closed with the shaggy lioness and the boar. He sought the lair and brood of the whelped lioness and was bloody prey to the Libyan beast.''Some have Hyas killed by a serpent, but mo ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
