The Tasmanian Giant Freshwater Crayfish is the largest freshwater invertebrate in the world and one of Australia's most extraordinary endemic species. Found only in Tasmania's clean, slow-moving rivers, it can live for several decades. These crayfish grow slowly, taking many years to reach full size. They play a vital role in freshwater ecosystems by breaking down organic material. Due to habitat loss and their slow reproduction, they are considered vulnerable. Our exhibit showcases this gentle giant and highlights the importance of freshwater conservation.
