Peltogastridae
The Peltogastridae are a family (biology), family of barnacles belonging to the bizarre parasitism, parasitic and highly synapomorphy, apomorphic infraclass Rhizocephala. The Peltogastridae are by far the largest family of Rhizocephala. They comprise 14 genera, 3 of which (''Lernaeodiscus'', ''Septodiscus'', and ''Triangulus'') were moved from the family Lernaeodiscidae. Genera These genera belong to the family Peltogastridae: * ''Briarosaccus'' Boschma, 1930 * ''Dipterosaccus'' Van Kampen & Boschma, 1925 * ''Galatheascus'' Boschma, 1929 * ''Lernaeodiscus'' Müller, 1862 * ''Ommatogaster'' Yoshida & Osawa, 2011 * ''Paratriangulus'' Høeg & Glenner, 2019 * ''Peltogaster'' Rathke, 1842 * ''Pterogaster'' Van Baal, 1937 * ''Septodiscus'' Van Baal, 1937 * ''Septosaccus'' Duboscq, 1912 * ''Temnascus'' Boschma, 1951 * ''Tortugaster'' Reinhard, 1948 * ''Trachelosaccus'' Boschma, 1928 * ''Triangulopsis'' Guérin-Ganivet, 1911 References External links * Barnacles Taxa named by ...

Rhizocephala
Rhizocephala are derived barnacles that parasitise mostly decapod crustaceans, but can also infest Peracarida, mantis shrimps and thoracican barnacles, and are found from the deep ocean to freshwater. Together with their sister groups Thoracica and Acrothoracica, they make up the subclass Cirripedia. Their body plan is uniquely reduced in an extreme adaptation to their parasitic lifestyle, and makes their relationship to other barnacles unrecognisable in the adult form. The name Rhizocephala derives from the Ancient Greek roots (, "root") and (, "head"), describing the adult female, which mostly consists of a network of thread-like extensions penetrating the body of the host. Description and lifecycle As adults they lack appendages, segmentation, and all internal organs except gonads, a few muscles, and the remains of the nervous system. Females also have a cuticle, which is never shed. Other than the minute larval stages, there is nothing identifying them as crustaceans or ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
