Entocytheridae
Entocytheridae is a family of freshwater crustaceans belonging to the order Podocopida. The family lives as ectosymbionts Ectosymbiosis is a form of Symbiosis, symbiotic behavior in which a Parasitism, parasite lives on the body surface of the Host (biology), host, including internal surfaces such as the lining of the Gastrointestinal tract, digestive tube and the d ... on other crustaceans.

Crustaceans
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) limb ...

Podocopida
The Podocopida are an order of ostracods in the subclass Podocopa. It is the most diverse of the four orders of ostracods, and also has a rich fossil record. Taxonomy The following suborders and unassigned taxa are contained in the order Podocopida: *Superfamily † Carbonitacea *Suborder Bairdiocopina *Suborder Cypridocopina *Suborder Cytherocopina *Suborder Darwinulocopina *Suborder Sigilliocopina See also *Cyprididae Cyprididae is "the most diverse group of freshwater ostracods". It contains over 1000 species, which represents 50% of the known species of freshwater ostracods (other speciose families include Candonidae, with 25%, and Limnocytheridae, with 1 ...

Ectosymbiosis
Ectosymbiosis is a form of symbiotic behavior in which a parasite lives on the body surface of the host, including internal surfaces such as the lining of the digestive tube and the ducts of glands. The parasitic species is generally an immobile, or sessile, organism existing off of biotic substrate through mutualism, commensalism, or parasitism. Ectosymbiosis is found throughout a diverse array of environments and in many different species. In some species the symbiotic environment provided by both the parasite and host are mutually beneficial. In recent research it has been found that these micro-flora will evolve and diversify rapidly in response to a change in the external environment, in order to stabilize and maintain a beneficial ectosymbiotic environment. Evolutionary History Ectosymbiosis has evolved independently many times to fill a wide variety of ecological niches, both temperate and extreme. Such temperate regions include the seas off the coast of Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
