Phronima
''Phronima'' is a genus of small, deep sea hyperiid amphipods of the family Phronimidae. It is found throughout the world's oceans, except in polar regions. ''Phronima'' species live in the pelagic zone of the deep ocean. Their bodies are semitransparent. Although commonly known as parasites, they are more technically correctly called parasitoids. Instead of constantly feeding on a live host, females attack salps, using their mouths and claws to eat the animal and hollow out its gelatinous shell. ''Phronima'' females then enter the barrel and lay their eggs inside, and then propels the barrel through the water as the larvae develop, providing them with fresh food and water. Classification The genus ''Phronima'' contains these species: *''Phronima atlantica'' *''Phronima bowmani'' *''Phronima bucephala'' *''Phronima colletti'' Bovallius, 1887 *''Phronima curvipes'' Vosseler, 1901 *''Phronima dunbari'' *''Phronima pacifica'' Streets, 1887 *''Phronima sedentaria'' (Forsskål, ...

Phronima Sedentaria
''Phronima sedentaria'' is a species of amphipod crustaceans found in oceans at a depth of up to . They are large in size relative to other members of the family Phronimidae. Individuals may be found inside barrel-like homes, created most commonly from the tunics of select species of tunicate, where they rear their young. ''P. sedentaria'' is known to employ multiple feeding strategies and other interesting behaviors, including daily vertical migration. The species is also known by the more common names “pram bug” and “barrel shrimp.” Description ''Phronima sedentaria'' is the largest and most abundant species in the family Phronimidae. Sexual dimorphism is reflected between male and female members in the more extended and prominent antennae of the males relative to the short, reduced ones of females. More obviously, the size discrepancy between males and females distinguishes them further. Females measure up to 42 mm (1.7 in) long, while males are only 15  ...

Hyperiidea
The Hyperiidea are a suborder of amphipods, small aquatic crustaceans. Unlike the other suborders of Amphipoda, hyperiids are exclusively marine and do not occur in fresh water. Hyperiids are distinguished by their large eyes and planktonic habitat. Most species of hyperiids are parasites or predators of salps and jellyfish in the plankton, although ''Themisto gaudichaudii'' and a few relatives are free-swimming predators of copepods and other small planktonic animals. Gallery Taxonomy According to Vinogradov ''et al.'' in 1996, 233 species of Hyperiidea are known. Some controversy exists as to the number of families in the Hyperiidea, being given as between 20 and 23 depending on whether groups like the Thaumatopsidae are considered distinct or not. The taxonomy of Hyperiidea currently accepted by the ''World Register of Marine Species'' is as follows: ;Infraorder Physocephalata Bowman & Gruner, 1973 * Parvorder Physocephalatidira Bowman & Gruner, 1973 ** Superfamily Phron ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
