Oithona
''Oithona'' is a planktonic crustacean genus found in marine, brackish, fresh water environments. ''Oithona'' has been described as the most ubiquitous and abundant 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) ... in the world's oceans. It was first described by Baird in 1843 using the species ''Oithona plumifera'' as taxon type. The following species are recognized: * ''Oithona aculeata'' Farran, 1913 * ''Oithona alvarezi'' Lindberg, 1955 * ''Oithona amazonica'' Burckhardt, 1913 * ''Oithona aruensis'' Früchtl, 1923 * ''Oithona atlantica'' Farran, 1908 * ''Oithona attenuata'' Farran, 1913 * ''Oithona australis'' Nishida, 1986 * ''Oithona bjornbergae'' Ferrari F.D. & Bowman, 1980 * ''Oithona bowmani'' Rocha C.E.F., 1986 * ''Oithona brevicornis'' Giesbrecht, 1891 * ''Oi ...

William Baird (physician)
William Baird (11 January 1803, in Eccles, Berwickshire – 27 January 1872) was a Scottish physician and zoologist best known for his 1850 work, ''The Natural History of the British Entomostraca''. Biography Baird studied at the High School of Edinburgh, before studying medicine at the universities of Edinburgh, Dublin, and Paris. He was a surgeon for the East India Company from 1823 to 1833, travelling to India, China and other countries, and taking a keen interest in those countries' natural history. He helped found the Berwickshire Naturalists' Club in 1829, and contributed regularly to its publications. Baird practised as a doctor in London until 1841, when he joined the zoology department of the British Museum (now part of the Natural History Museum). He is buried in the Kensal Green Cemetery, London. Work Baird's most important work, ''The Natural History of the British Entomostraca'', was published by the Ray Society in 1850. He published many other papers on diver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

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] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
