Overview

The Australian freshwater limpet or Tasmanian freshwater limpet, scientific name Ancylastrum cumingianus, is a species of air-breathing freshwater snail or freshwater limpet, an aquatic pulmonate gastropod mollusc in the family Planorbidae. This species is endemic to freshwater lakes in the Central Plateau of Tasmania.

Ancylastrum cumingianus faces severe threats from habitat degradation and water pollution in its freshwater environments. The species' limited distribution makes it particularly vulnerable to localized environmental changes, while sedimentation and agricultural runoff have significantly impacted water quality in its native range. Urban development and dam construction have further fragmented suitable habitat areas.
