Hemioniscidae
The Hemioniscidae are a family of marine isopod crustaceans in the suborder Cymothoida. The original description was made by Bonnier in 1900. Members of this family are parasitic on cirripede barnacles. The family contains these genera and species: *'' Hemioniscus'' Buchholz, 1866 :*''Hemioniscus balani ''Hemioniscus balani'', a species of isopod crustacean, is a widespread parasitic castrator of barnacle in the northern Atlantic Ocean.

Hemioniscus Balani
''Hemioniscus balani'', a species of isopod crustacean, is a widespread parasitic castrator of barnacle in the northern Atlantic Ocean. Its range extends from Norway to the Atlantic coast of France, and as far west as Massachusetts. It is also commonly found on the Pacific coast of North America; it is not known if the Pacific and Atlantic populations are the same species, or if the Pacific population exists following human-assisted introduction. Life history ''H. balani'' parasitically castrates adults of several species of barnacles, including '' Semibalanus balanoides'', ''Chthamalus fissus'', '' Chthamalus dalli'', and ''Balanus glandula''. Rarely does more than one ''H. balani'' parasitize the same host, but under conditions of heavy infestation, a single barnacle may contain as many as seven ''H. balani'' individuals. Both the isopod parasite and its barnacle host are hermaphroditic crustaceans with a free-swimming larva and a sessile adult. ''H. balani'' is a protandro ...

Cymothoida
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing. Classification Cymothoida contains these superfamilies and families: *Superfamily Anthuroidea Leach, 1814 **Antheluridae Poore & Lew Ton, 1988 **Anthuridae Leach, 1814 **Expanathuridae Poore, 2001 **Hyssuridae Wägele, 1981 **Leptanthuridae Poore, 2001 **Paranthuridae Menzies & Glynn, 1968 *Superfamily Cymothooidea Leach, 1814 ** Aegidae White, 1850 **Anuropidae Stebbing, 1893 ** Barybrotidae Hansen, 1890 ** Cirolanidae Dana, 1852 **Corallanidae Hansen, 1890 **Cymothoidae Leach, 1818 ** Gnathiidae Leach, 1814 **Protognathiidae Wägele & Brandt, 1988 **Tridentellidae Bruce, 1984 *Superfamily Cryptoniscoidea Kossmann, 1880 ** Asconiscidae Bon ...

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 opi ...
