Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Sea Cucumber
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ...

Synaptidae
Synaptidae is a family of sea cucumbers that have no tube feet, tentacle ampullae, retractor muscles, respiratory trees, or cuvierian tubules. They also lack radial canals of the water-vascular system, with only the circumoral ring present. Synaptids have elongated bodies, and their size varies significantly from small to quite large. ''Synapta maculata'' grows to two metres in length. They are quite active, moving by means of waves of peristaltic contractions. Their tegument is somewhat sticky because of the anchor-like spicules that project through the skin. Genera According to World Register of Marine Species: * '' Anapta'' Semper, 1867 -- 3 species * '' Dactylapta'' Clark, 1908 -- 1 species * †'' Eoleptosynapta'' Reich in Reich & Ansorge, 2014 -- 1 species * †'' Eorynkatorpa'' Reich in Reich & Ansorge, 2014 -- 1 species * '' Epitomapta'' Heding, 1928 -- 3 species * '' Euapta'' Östergren, 1898 -- 4 species * '' Eupatinapta'' Heding, 1928 -- 2 species * '' Labidoplax' ...

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 ...

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 ...

Euapta Godeffroyi
''Euapta godeffroyi'', the sticky snake sea cucumber, is a species of sea cucumber in the family Synaptidae Synaptidae is a family of sea cucumbers that have no tube feet, tentacle ampullae, retractor muscles, respiratory trees, or cuvierian tubules. They also lack radial canals of the water-vascular system, with only the circumoral ring present. S .... It is found on coral reefs in the tropical Indo-Pacific region. Description ''E. godeffroyi'' is a long, slender sea cucumber growing to a length of about . A ring of fifteen feathery tentacles encircle the mouth. The body colour is creamy white with blotches of grey and a pair of longitudinal brown or greenish stripes. The spicules (microscopic calcareous structures that project through the skin) are a mixture of anchors and perforated plates with large holes. Distribution and habitat ''E. godeffroyi'' is native to the tropical Indo-Pacific region. Its range extends from the Red Sea and Madagascar to Hawaii and Easter Isla ...

Euapta Lappa
''Euapta lappa'', the beaded sea cucumber, is a species of sea cucumbers in the family Synaptidae in the phylum Echinodermata. It is found on coral reefs in the Caribbean region. Description In appearance, the beaded sea cucumber resembles a long worm rather than a sea cucumber. It can reach up to a metre (yard) in length and has a diameter of up to . It lengthens and shortens repeatedly and when disturbed, the normally flaccid body retracts vigorously to a fraction of its original length. It has no internal respiratory tree, nor does it have tube feet, and the body surface is covered by rounded ridges. The skeletal structure consists of many tiny calcareous plates embedded in the cuticle. Little hooks project from these ossicles and make the body feel sticky to the touch. At the anterior (front) of the animal there is a ring of fifteen branched feeding tentacles. The body colour is pale brown or grey, often with white flecks or darker, longitudinal streaks and transverse banding ...
