General Description

Shells longer than they are tall and are quite deep bodied. All possess the dark horny outer layer on the shell and are distinguished on slight differences in their shell shape, muscle attachments and gills. The shell ranges in size from 3.5-9 cm.


Freshwater mussels are filter feeders and live burrowed into the sediment so that only part of their shell remains visible. Water is drawn via siphons into the gills where oxygen is extracted and food particles are filtered out. Newly released eggs hatch into a larval stage that is parasitic on freshwater fishes. This stage gets carried by its fish host and eventually detaches to change into the typical shell form that settles in the river bed.


In rivers of Victoria and southern New South Wales.


Rivers and streams. Burrows in soft sediment, often at the edges of the water.
