Themisto (crustacean)
''Themisto'' is a genus of marine amphipods in the family Hyperiidae. Their distribution is cosmopolitan. Ecological role ''Themisto'' are obligate carnivores. ''Themisto gaudichaudii'' has been found to feed opportunistically on copepods and chaetognaths, as juveniles also on diatoms. ''Themisto'' are important prey in many food webs. For example, ''Themisto gaudichaudii'' reaches high densities (up to 61 individuals/m3) in Kerguelen waters and is a major food item for blue petrels, thin-billed prions, Antarctic prions, common diving petrels, and southern rockhopper penguins. In the Barents Sea, '' Themisto libellula'' is very abundant in the Arctic waters and important food item for cod, polar cod, and marine mammals near the ice edge, whereas '' Themisto abyssorum'' is important in Atlantic/boreal waters. Life history ''Themisto gaudichaudii'' matures at lengths between or more. Reproduction can be nearly continuous but becomes more seasonal at higher latitudes. The offspri ...

Hyperiidea
The Hyperiidea are a suborder of amphipods, small aquatic crustaceans. Unlike the other suborders of Amphipoda, hyperiids are exclusively marine and do not occur in fresh water. Hyperiids are distinguished by their large eyes and planktonic habitat. Most species of hyperiids are parasites or predators of salps and jellyfish in the plankton, although ''Themisto gaudichaudii'' and a few relatives are free-swimming predators of copepods and other small planktonic animals. Gallery Taxonomy According to Vinogradov ''et al.'' in 1996, 233 species of Hyperiidea are known. Some controversy exists as to the number of families in the Hyperiidea, being given as between 20 and 23 depending on whether groups like the Thaumatopsidae are considered distinct or not. The taxonomy of Hyperiidea currently accepted by the '' World Register of Marine Species'' is as follows: ;Infraorder Physocephalata Bowman & Gruner, 1973 * Parvorder Physocephalatidira Bowman & Gruner, 1973 ** Superfamily P ...

Hyperia Macrocephala
''Hyperia macrocephala'' is a species of zooplankton, an amphipod in the family Hyperiidae The Hyperiidae are a family of amphipods, containing these genera: *'' Euthemisto'' Bovallius, 1887 *'' Hyperia'' Latreille ''in'' Desmarest, 1823 *'' Hyperiella'' Bovallius, 1887 *'' Hyperoche'' Bovallius, 1887 *'' Laxohyperia'' M. Vinogradov & .... Etymology The name ''Hyperia macrocephala'' comes from the Latin "large head". Description This species can grow to 29 mm. The head of ''Hyperia macrocephala'' is shorter than the combined length of the first two pereonites. Specimens that are large and mature have CX IV that are pointed and laterally projecting. The P III-IV have many short, non-uniform setae on ART 5 and 6. The P V-VII are naked, and have a short cluster of setae apparently on only on the anterodistal margins of ART 2 of P V and VII. There are sharply pointed posterodistal corners on the epimeral plates. There is a strongly convex shape to the posterior margin of th ...

Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Dwight Dana
James Dwight Dana FRS FRSE (February 12, 1813 – April 14, 1895) was an American geologist, mineralogist, volcanologist, and zoologist. He made pioneering studies of mountain-building, volcanic activity, and the origin and structure of continents and oceans around the world. His zoological author abbreviation is Dana. Early life and career Dana was born February 12, 1813, in Utica, New York. His father was merchant James Dana (1780–1860) and his mother was Harriet Dwight (1792–1870). Through his mother he was related to the Dwight New England family of missionaries and educators including uncle Harrison Gray Otis Dwight and first cousin Henry Otis Dwight. He showed an early interest in science, which had been fostered by Fay Edgerton, a teacher in the Utica high school, and in 1830 he entered Yale College in order to study under Benjamin Silliman the elder. Graduating in 1833, for the next two years he was teacher of mathematics to midshipmen in the Navy, and sailed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List o ...
