Tasmanian giant freshwater crayfish
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 above sea level in northern Tasmania, an island-state of Australia. It is listed as an endangered species on the IUCN Red List due to overfishing and habitat degradation, and it has been prohibited to catch the crayfish since 1998.

The diet of the freshwater crayfish varies with age, but predominantly consists of decaying wood, leaves and their associated microbes. They may also eat small fish, insects, rotting animal flesh and other detritus when available. "A. gouldi" is very long-lived, surviving for up to 60 years.

When fully mature the species has no natural predators due to its large size, while smaller individuals can be prey of platypus, river blackfish and rakali.
