Lynceidae is a family of clam shrimp in the order Laevicaudata. There are about 5 genera and more than 20 described species in Lynceidae. [1] [2] [3]
These five genera belong to the family Lynceidae:
Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Cladocera, Notostraca and the Devonian Lepidocaris. They are mostly small, freshwater animals that feed on plankton and detritus.
Clam shrimp are a taxon of bivalved branchiopod crustaceans that resemble the unrelated bivalved molluscs. They are extant, and known from the fossil record, from at least the Devonian period and perhaps before. They were originally classified in a single order Conchostraca, which later proved to be paraphyletic, being separated into three different orders: Cyclestherida, Laevicaudata, and Spinicaudata.
Anostraca is one of the four orders of crustaceans in the class Branchiopoda; its members are also known 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. 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.
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.
The graceful clam shrimp is a species of clam shrimp found in Texas, northern Florida and possibly other regions in between.
Bresilioidea is a superfamily of shrimp. It is likely to be an artificial group, containing five families which may or may not be related.
Chirocephalidae is a family of fairy shrimp, characterised by a reduced or vestigial maxilla, more than two setae on the fifth endite, divided pre-epipodites and widely separated seminal vesicles. It consists of the following eight genera, including the genera formerly placed in the families Linderiellidae and Polyartemiidae:
Stenopodidae is a family of decapods in the order Decapoda. There are about 6 genera and more than 30 described species in Stenopodidae.
Bosminidae is a family of anomopods in the order Diplostraca. There are at least 3 genera and 40 described species in Bosminidae.
Macrothricidae is a family of anomopods in the order Diplostraca. There are about 17 genera and at least 80 described species in Macrothricidae.
Podonidae is a family of onychopods in the order Diplostraca. There are about 8 genera and at least 20 described species in Podonidae.
Diaperini is a tribe of darkling beetles in the family Tenebrionidae. There are about 13 genera and at least 40 described species in Diaperini.
Detonidae is a family of woodlice in the order Isopoda. There are at least 3 genera and more than 30 described species in Detonidae.
Janiridae is a family of isopods in the order Isopoda. There are more than 20 genera and 190 described species in Janiridae.
Cylisticidae is a family of woodlice in the order Isopoda. There are at least 4 genera and more than 60 described species in Cylisticidae.
Lynceus brachyurus, known generally as the holarctic clam shrimp or common lynceus, is a species of clam shrimp in the family Lynceidae. It is found in Europe.
Lynceus is a genus of clam shrimp in the family Lynceidae. There are about 13 described species in Lynceus.
Raymondionyminae is a subfamily of snout and bark beetles in the family Brachyceridae. There are at least three genera and two described species in Raymondionyminae.
Chydoridae is a family of water fleas in the order Anomopoda. There are more than 50 genera and 520 described species in Chydoridae.
