Rhynchochydorus australiensis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Rhynchochydorus australiensis faces significant pressure from agricultural expansion and urban development across its limited range in southeastern Australia. Water extraction and dam construction have altered natural flow regimes in the freshwater systems this species depends upon. Introduced aquatic species and pollution from agricultural runoff further degrade the specialized microhabitats required by this endemic cladoceran.
