Identifying features

​A round shaped oyster with irregular ridges and flaking or brittle edges to its thick shell.  The shell halves or valves are different with one curved and one flat.  Colour is brownish to whitish or cream depending on its habitat.


Found in the sandy or silty subtidal zone from 2-20 metres on the east coast of Tasmania.  Attaches to rocks and shells in sheltered areas and channels.  Sometimes forms dense beds or layered reefs in areas with strong tidal currents.

Fishing Information

Usually taken recreationally by diving.  Closely related to the European oyster, the native oyster is considered a delicacy by lovers of this gourmet food.


Sponges growing on shells may cause skin irritations.
