Bosminidae is a family of anomopods in the order Diplostraca. There are at least three genera and 40 described species in Bosminidae. [1] [2] [3] [4]
The order Notostraca, containing the single family Triopsidae, is a group of crustaceans known as tadpole shrimp or shield shrimp. The two genera, Triops and Lepidurus, are considered living fossils, with similar forms having existed since the end of the Devonian, around 360 million years ago. They have a broad, flat carapace, which conceals the head and bears a single pair of compound eyes. The abdomen is long, appears to be segmented and bears numerous pairs of flattened legs. The telson is flanked by a pair of long, thin caudal rami. Phenotypic plasticity within taxa makes species-level identification difficult, and is further compounded by variation in the mode of reproduction. Notostracans are omnivores living on the bottom of temporary pools and shallow lakes.
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.
Acanthametropus is a genus of mayflies in the family Acanthametropodidae. There are at least two described species in Acanthametropus.
Bosmina is a genus in the order Cladocera, the water fleas. Its members can be distinguished from those of Bosminopsis by the separation of the antennae; in Bosminopsis, the antennae are fused at their bases.
Rhithrogena is a genus of flatheaded mayflies in the family Heptageniidae. There are at least 150 described species in Rhithrogena.
Callibaetis is a genus of small minnow mayflies in the family Baetidae. There are at least 30 described species in Callibaetis.
Neoephemeridae is a family of large squaregill mayflies in the order Ephemeroptera. There are at least four genera and about 17 described species in Neoephemeridae.
Drunella is a genus of spiny crawler mayflies in the family Ephemerellidae. There are at least 20 described species in Drunella.
Ametropodidae is a family of mayflies in the order Ephemeroptera. There are at least three genera and three described species in Ametropodidae.
Callibaetis montanus is a species of small minnow mayfly in the family Baetidae. It is found in Central America and North America. In North America its range includes all of Mexico and the southwestern United States.
Drunella spinifera is a species of spiny crawler mayfly in the family Ephemerellidae. It is found in southwestern and northern Canada and the western United States and Alaska.
Macrothricidae is a family of anomopods in the order Diplostraca. There are about 17 genera and at least 80 described species in Macrothricidae.
Cactus is a genus of anomopods in the family Macrothricidae. There is only one described species, Cactus cactus. C. cactus can be found in Chile.
Podonidae is a family of onychopods in the order Diplostraca. There are about 8 genera and at least 20 described species in Podonidae. A lot of them are non-native species, many of which pose a great threat to aquatic ecosystems.
Evadne is a genus of onychopods in the family Podonidae. There are at least four described species in Evadne.
Ameletus cryptostimulus is a species of combmouthed minnow mayfly in the family Ameletidae. It is found in southeastern Canada and the eastern United States.
Epeorus vitreus is a species of flatheaded mayfly in the family Heptageniidae. It is found in southeastern Canada and the eastern United States.
Pseudiron is a genus of crabwalker mayflies in the family Pseudironidae. There is one described species in Pseudiron, Pseudiron centralis.
Iswaeon is a genus of small minnow mayflies in the family Baetidae. There are at least three described species in Iswaeon.
Penelomax is a genus of spiny crawler mayflies in the family Ephemerellidae. There is one described species in Penelomax, P. septentrionalis.
