Branchinectidae
Branchinectidae is a family (biology), family in the order Anostraca (fairy shrimp), containing two genera – ''Branchinecta'' and ''Archaebranchinecta''. The majority of the species are in the genus ''Branchinecta'', with only ''Archaebranchinecta pollicifera'' and the fossil ''Archaebranchinecta barstowensis'' in the second genus.

Anostraca
Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are referred to as fairy shrimp. They live in vernal pools and hypersaline lakes across the world, and they have even been found in deserts, ice-covered mountain lakes and Antarctic ice. They are usually long (exceptionally up to ). Most species have 20 body segments, bearing 11 pairs of leaf-like ''phyllopodia'' (swimming legs), and the body lacks a carapace. They swim "upside-down" and feed by filtering organic particles from the water or by scraping algae from surfaces. They are an important food for many birds and fish, and some are cultured and harvested for use as fish food. There are 300 species spread across 8 families. Description The body of a fairy shrimp is elongated and divided into segments. The whole animal is typically long, but one species, '' Branchinecta gigas'' does not reach sexual maturity until it reaches long, and can grow to long. The exoskeleton is thin and ...

Archaebranchinecta Barstowensis
''Archaebranchinecta barstowensis'' is a species of fairy shrimp (Anostraca) that inhabited California during the Middle Miocene (). Its fecal material is abundant in the concretions from the Barstow Formation. A limited number of whole specimens have been found, and they represent the "best-preserved fossil anostracan known to date". The closest relative of ''A. barstowensis'' appears to be '' Archaebranchinecta pollicifera'' from the surroundings of Lake Titicaca, and the two have been separated from the genus ''Branchinecta ''Branchinecta'' is a genus of crustacean Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipod ...'' as the new genus '' Archaebranchinecta''.

Eugen Von Daday
Eugen von Daday or Jenő von Daday (1855–1920) was a Romanian professor of zoology in Hungary in the late 19th and early 20th century. Daday was an expert on aquatic invertebrates, particularly crustaceans. Daday collected and identified many species and genera within the borders of the Hungarian empire, and received samples of invertebrates from collectors around the world. After his death in 1920, Daday's collection of crustaceans was acquired by the Hungarian Natural History Museum The Hungarian Natural History Museum ( hu, Magyar Természettudományi Múzeum) in Budapest, dating back to 1802, houses the largest natural history collections of Hungary and the region. History of the museum Foundation In 1802, Count Feren ....

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 ...
