Palaemon Modestus
''Palaemon modestus'', the Siberian prawn, is a species of Fresh water, freshwater Caridea, shrimp from eastern Asia. A revision to ''Palaemon (crustacean), Palaemon'' in 2013 moved ''Palaemon modestus'' to the ''Palaemon'' genus from the ''Exopalaemon'' genus.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Caridea
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp. Biology Carideans are found in every kind of aquatic habitat, with the majority of species being marine. Around a quarter of the described species are found in fresh water, however, including almost all the members of the species-rich family Atyidae and the Palaemonidae subfamily Palaemoninae. They include several commercially important species, such as ''Macrobrachium rosenbergii'', and are found on every continent except Antarctica. The marine species are found at depths to , and from the tropics to the polar regions. In addition to the great variety in ...

Palaemon (crustacean)
''Palaemon'' is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus ''Palaemon'' is probably paraphyletic. Molecular data suggest that ''Palaemonetes'', as well as the genera ''Exopalaemon'' and '' Couteriella'', are nested within ''Palaemon''. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments. Members The genus contains the following species: *'' Palaemon adspersus'' Rathke, 1837 *''Palaemon affinis'' H. Milne-Edwards, 1837 *''Palaemon capensis'' (De Man ''in'' M. Weber, 1897) *'' Palaemon carteri'' (Holthuis, 1950) *''Palaemon concinnus'' Dana, 1852 (mangrove prawn) *''Palaemon curvirostris'' Nguyên, 1992 *''Palaemon debilis'' Dana, 1852 *''Palaemon dolospinus'' Walker & Poore, 2003 *''Palaemon elegans'' Rathke, 1837 (rockpool prawn) *''Palaemon floridanus'' Chace, 1942 (Florida grass shrimp) *''Palaemon gladiator'' Holthuis, 1950 *''Palaemon gracilis'' (Smith, ...

Exopalaemon
''Palaemon'' is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus ''Palaemon'' is probably paraphyletic. Molecular data suggest that '' Palaemonetes'', as well as the genera '' Exopalaemon'' and '' Couteriella'', are nested within ''Palaemon''. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments. Members The genus contains the following species: *''Palaemon adspersus'' Rathke, 1837 *'' Palaemon affinis'' H. Milne-Edwards, 1837 *'' Palaemon capensis'' (De Man ''in'' M.

Palaemonidae
Palaemonidae is a family of shrimp in the order Decapoda. Many species are carnivores that eat small invertebrates, and can be found in any aquatic habitat except the deep sea. One significant genus is ''Macrobrachium'', which contains commercially fished species. Others inhabit coral reefs, where they associate with certain invertebrates, such as sponges, cnidarians, mollusks, and echinoderms, as cleaner shrimps, parasites, or commensals. They generally feed on detritus, though some are carnivores and hunt tiny animals. The family contains more than 1200 species in 160 genera. The genera were formerly split into two subfamilies, but in 2015, molecular and morphological research determined that the subfamily groupings were invalid. At the same time, the members of the families Gnathophyllidae and Hymenoceridae were incorporated into the Palaemonidae. Genera The following genera are recognised: *'' Actinimenes'' *'' Alburnia'' *'' Allopontonia'' *'' Altopontonia'' *' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
