More than 1,300 described species of freshwater crabs are known, out of a total of 6,700 species of crabs across all environments. [1] The total number of species of freshwater crabs, including undescribed species, is thought to be up to 65% higher, potentially up to 2,155 species, although most of the additional species are currently unknown to science.

Austrothelphusa transversa (von Martens, 1868), also known as the inland crab, freshwater crab, or tropical freshwater crab [3] is a species of freshwater crab endemic to Australia. [1] A. transversa is the most widely-dispersed species of its genus, as it has adaptations giving it a high tolerance to drought and arid conditions. [4]
Crabs are members of infraorder Brachyura. They are crustaceans with five pairs of legs, the first pair modified to form a pair of pincers, a flattish shell, and a short, broad abdomen folded under its thorax.
Arcopotamonautes platynotus is a species of freshwater crab which is endemic to Lake Tanganyika, where it is the only freshwater crab outside the genus Platythelphusa. [2] Although primarily aquatic, A. platynotus is sometimes seen out of water, and can survive for many hours without water. [1]
The genus is the only evolutionary radiation of crabs to have occurred in a freshwater lake, and it occurred recently, probably since the Pliocene. [2] This parallels the better known radiation of cichlid fishes in Lake Tanganyika. [3] Only one other species of freshwater crab is found in Lake Tanganyika, Potamonautes platynotus. [2]
Parathelphusa pantherina, commonly known as the "panther crab", is a variety of freshwater crab from Indonesia from the family of the Gecarcinucidae . The scientific name of the species was published for the first time in 1902 by Schenkel.
Potamonautes sidneyi is a species of freshwater crab in the family Potamonautidae. The common name is the Natal river crab or Sidney's river crab , [ 1 ] although they may also be referred to as "river crabs", "fresh water crabs" or "land crabs".
The crabs are collected by certain crab catching communities or experts belonging to certain castes and tribes. Then they are sold in the weekly markets. They are not exhibited in special crab markets but rather in fish markets. The species is hardy to withstand without water in moist and can airbreath and remain live without food for a few days.
