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.

Most fish are stenohaline, which means they are restricted to either salt or fresh water and cannot survive in water with a different salt concentration than they are adapted to. However, some fish show a tremendous ability to effectively osmoregulate across a broad range of salinities; fish with this ability are known as euryhaline species, e ...
Species listed here have an annual tonnage in excess of 160,000 tonnes. This table includes mainly food fish species, but also listed are crustaceans (crabs and shrimps), cephalopods (squids and cuttlefishs), bivalves, and a reptile (softshell turtle).
Consequently, they can be threatening, especially to crabs, shrimps, and smaller fish, and are known for hopping out of tanks, so make sure yours is covered. Scientific name oxycirrhites typus ...

The following list of known freshwater fish species, subspecies, and hybrids occurring in Washington state is taken from Wydoski and Whitney(2003). Some scientific names have been updated or corrected. Trout nomenclature follows Behnke et al.(2002). Asterisks denote introduced fishes.
Crabs are prepared and eaten as a dish in many different ways all over the world. Some species can be eaten whole, including the shell, as soft-shell crabs; with other species, just the claws or legs are eaten. The latter is particularly common for larger crabs, such as the snow crab.
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
