Branchinella lithaca, the Stone Mountain fairy shrimp, is a species of crustacean in the family Thamnocephalidae. It was collected on Stone Mountain, DeKalb County, Georgia in 1940, and has not been seen since. [2] It is listed as Critically Endangered on the IUCN Red List. [1]
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 6–25 mm (0.24–0.98 in) long. Most species have 20 body segments, bearing 11 pairs of leaf-like phyllopodia, 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, with the exception of Branchinecta gigas, or "giant fairy shrimp", which is itself a predator of other species of anostracans. 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.
Asellus aquaticus is a freshwater crustacean resembling a woodlouse. It is known by various common names including pond slater, water louse, aquatic sowbug, water hoglouse and cress bug.
Anaspididae is a family of freshwater crustacean that is endemic to Tasmania, Australia. The family contains 3 genera and 5 species. This group of crustaceans are considered living fossils. They are commonly and collectively known as the Tasmanian anaspid crustaceans.
Linderiella occidentalis is a species of fairy shrimp native to California. It is a small crustacean in the family Chirocephalidae. It has a delicate elongated body, large stalked compound eyes, no carapace, and eleven pairs of swimming legs. It glides gracefully upside down, swimming by beating its legs in a complex, wavelike movement that passes from front to back. Like other fairy shrimp, L. occidentalis feeds on algae, bacteria, protozoa, rotifers and detritus.
The conservancy fairy shrimp is an endangered small crustacean in the family Branchinectidae. It ranges in size from about 1.25 centimetres (0.49 in) to 2.5 centimetres (0.98 in) long. This species is endemic to California in the United States.
Branchinecta is a genus of fairy shrimp in family Branchinectidae. It includes around 50 species, found on all continents except Australia. Branchinecta gigas, the giant fairy shrimp, is the largest species in the order, with a length of up to 10 centimetres (4 in), and Branchinecta brushi lives at the highest altitude of any crustacean, at 5,930 metres (19,460 ft), a record it shares with the copepod Boeckella palustris. A new genus, Archaebranchinecta was established in 2011 for two species previously placed in Branchinecta.
Branchinecta longiantenna is a rare species of crustacean in the family Branchinectidae and the order Anostraca, the fairy shrimp. Its common name is longhorn fairy shrimp. It is endemic to California in the United States, where there are only four known populations. It is a federally listed endangered species of the United States.
The vernal pool fairy shrimp, Branchinecta lynchi, is a species of freshwater crustacean in the family Branchinectidae. It is endemic to the U.S. states of Oregon and California, living in vernal pools as well as non-vernal pool habitat. They range in size from 0.43 to 0.98 inches long. Vernal pool fairy shrimp are listed as a vulnerable species on the IUCN Red List, and has been listed as Federally Threatened species since 1994.
Branchinecta sandiegonensis is a rare species of crustacean in the family Branchinectidae and the order Anostraca, the fairy shrimp. Commonly known as the San Diego fairy shrimp, it is named after the vernal pools found in San Diego County, California, where this species was originally discovered. It is also a federally listed endangered species of the United States.
Branchinella alachua is a species of crustacean in the family Thamnocephalidae. It was described in 1953 by Ralph W. Dexter based on material collected in 1947 by I. J. Cantrall; 11 male individuals of the new species were discovered among Cantrall's collection of Streptocephalus seali. B. alachua is only known from the type locality, a temporary pool in Alachua County, Florida, from which its specific epithet derives. It is listed as an endangered species on the IUCN Red List.
Branchinella is a genus of crustaceans in the family Thamnocephalidae. This fairy shrimp genus is found across many parts of the world, but especially western Australia and southern Africa.
Branchinella apophysata is a species of crustacean in the family Thamnocephalidae. It is endemic to Australia, where it is known only from its type locality, a shallow pool on Mount Margaret, near Laverton, Western Australia. It is most closely related to other Australian species, including B. affinis, B. denticulata, B. latzi, B. longirostris and B. probiscida.
Branchinella denticulata is a species of crustacean in the family Thamnocephalidae. It is endemic to Australia.
Branchinella simplex is a species of crustacean in the family Thamnocephalidae. It is endemic to Australia.
Branchinella wellardi is a species of crustacean in the family Thamnocephalidae. It is endemic to Australia.
Dexteria floridana is an extinct species of fairy shrimp in the family Chirocephalidae, the only species in the genus Dexteria. It was endemic to Florida, where it was known from a single pool, south of Gainesville. It was originally described by Ralph W. Dexter in 1953 as a species of Eubranchipus. The species was declared extinct on October 5, 2011 because it was found that the only known pool of water that contained the known population was filled in for development, thereby killing the shrimps.
Parartemia contracta is a species of fairy shrimp in the family Parartemiidae and is commonly found in Australia.
Streptocephalus woottoni, with the common name Riverside fairy shrimp, is a rare species of crustacean in the family Streptocephalidae. It is native to Southern California in the United States, and northern Baja California in northwest Mexico.
Branchinecta gigas is a species of fairy shrimp that lives in western Canada and the United States. It is the largest species of fairy shrimp, growing up to 86 mm (3.4 in) long. It is known commonly as the giant fairy shrimp.
Parastreptocephalus is a subgenus of the fairy shrimp genus Streptocephalus, characterised by features of the male antennae and the tetrahedral shape of the eggs. It comprises six species:
