Endangered
Balan spiny crayfish
Euastacus balanensis
Balan spiny crayfish is a spiny crayfish in the family Parastacidae (order Decapoda) — Euastacus balanensis, recorded as Endangered and tied to Australia.
The spiny crayfish
Southern hemisphere crayfishes include the Australian Euastacus group — large, long-lived animals of cool forest streams.
Decapods are ten-legged crustaceans — crabs, shrimps, and crayfishes. Freshwater species here are usually tied to a drainage.
Range and habitat
Balan spiny crayfish is recorded from Australia.
GBIF currently lists 54 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Habits
Freshwater crayfishes and crabs walk the bed. Dams, silt, and introduced species cut a drainage into fragments they cannot cross.
Crayfishes and crabs need cover and clean water. A named form from one creek is not interchangeable with the next drainage.
In crisis
Balan spiny crayfish is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
