Oncaeidae
Oncaeidae is a family of copepods, containing the following genera: *'' Archioncaea'' Böttger-Schnack & Huys, 1997 *'' Conaea'' Giesbrecht, 1891 *'' Epicalymma'' Heron, 1977 *'' Monothula'' Böttger-Schnack & Huys, 2001 *''Oncaea ''Oncaea'' is a genus of copepods.

Poecilostomatoida
Poecilostomatoida are an suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida Description The classification of these copepods has been established on the basis of the structure of the mouth. In poecilostomatoids the mouth is represented by a transverse slit, partially covered by the overhanging labrum which resembles an upper lip. Although there is variability in the form of the mandible among poecilostomatoids, it can be generalized as being falcate (sickle-shaped). The antennules are frequently reduced in size and the antennae modified to terminate in small hooks or claws that are used in attachment to host organisms. Life cycle As with many crustaceans, larval development is metamorphic with immature forms differing greatly from those of adults. Embryos are carried in paired or single sacs attached to first abdominal somite (as seen in the illustration of the female '' Sapphirina darwinii ...

Oncaea Venusta
''Oncaea venusta'' is a species of copepod with a cosmopolitan distribution, but lacking from the Arctic Ocean. Females are long, while males are only long. The front of the head is unusually wide, and the body is brightly coloured, usually yellow–orange, but sometimes red. ''O. venusta'' feeds on a variety of zooplankton and phytoplankton Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Ph .... References Poecilostomatoida Crustaceans described in 1843 {{copepod-stub ...

Wilhelm Giesbrecht
Wilhelm Giesbrecht (1854–1913) was a Prussian zoologist, specialising in copepods, during the "golden age of copepodology". Giesbrecht was born in Gdańsk in 1854, and was educated in Kiel, where in 1881 he earned a Ph.D. in Baltic copepods under Professor Karl Möbius. He then moved to Naples to work at the zoological station there, staying there for the remainder of his life. His most famous work is the 1892 monograph Systematik und Faunistik der pelagischen Copepoden des Golfes von Neapel und der angrenzenden Meeres-Abschnitte' ("Systematics and faunistics of the pelagic copepods of the Gulf of Naples and neighbouring seas"). In 1904, at the request of Anton Dohrn, Giesbrecht was made an honorary professor Honorary titles (professor, reader, lecturer) in academia may be conferred on persons in recognition of contributions by a non-employee or by an employee beyond regular duties. This practice primarily exists in the UK and Germany, as well as in m .... He is commemorated ... [...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 opini ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of ...
