An extinct Tasmanian crayfish, the Short-Tailed Rain Crayfish (ombrastacoides parvicaudatus), has been rediscovered in two creeks near Queenstown. The crayfish was first documented in the 1970s and 1980s but was not seen for decades until an environmental survey by Hydro Tasmania. The crayfish was found in Lake Burbury, a known hotspot for endemic crayfish species. Crayfish expert Associate Professor Alastair Richardson helped identify six crayfish species during the survey and was particularly encouraged by the discovery of a female Short-Tailed Rain Crayfish carrying eggs.
