Streptocephalus dendyi is a species of crustacean in the family Streptocephalidae. It is endemic to South Africa.
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.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
Dendy's toadlet is a species of frog in the family Myobatrachidae. It is endemic to Australia. Its natural habitats are temperate forests, temperate grassland, rivers, intermittent rivers, swamps, and intermittent freshwater marshes.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
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.
