Austrogammarus australis
Austrogammarus australis is a crustacean in the family Paramelitidae (order Amphipoda), recorded as Critically Endangered.
The crustacean
Austrogammarus australis is a crustacean in the family Paramelitidae (order Amphipoda).
Range and habitat
It is endemic to Australia and until recently thought to be extinct, but surveys conducted in the Dandenong Ranges have revealed small populations. Recent works have been undertaken to improve habitat quality and extend the range of the invertebrate. Found in the same ecological niche as similar amphipod species, the distinctive "sideways" swimming style and somewhat "hairy" appearance of the amphipod differentiate it.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Habits
Crayfishes and crabs need cover and clean water. A named form from one creek is not interchangeable with the next drainage.
In crisis
Austrogammarus australis is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
