The Tasmanian giant freshwater crayfish (Astacopsis gouldi), also called Tasmanian giant freshwater lobster, is the largest freshwater invertebrate and the largest freshwater crayfish species in the world. The species is only found in the rivers below 400 metres (1,300 ft) above sea level in northern Tasmania, an island-state of Australia.
Euastacus crayfish are distinguished from the smooth-shelled Cherax species by the short robust spikes on their claws and carapace, and frequently, their larger size. Many Euastacus species grow to a relatively large size, with the Murray River crayfish ( Euastacus armatus ) being the second largest freshwater crayfish species in the world.
Crayfish usually have limited home range and so they rest, digest, and eliminate their waste, most commonly in the same location each day. Feeding exposes the crayfish to risk of predation, and so feeding behaviour is often rapid and synchronised with feeding processes that reduce such risks — eat, hide, process and eliminate.
A second line of spines is generally poorly developed, being absent to tiny in smaller animals, under 30 mm (1.2 in), and tiny to small on larger specimens. There are two to three spines on segments two and three in a second line on most crayfish above 30 mm (1.2 in), rarely on segments four and five and absent on segment six.
