Abundantly common throughout intertidal areas of the Solitary Islands Marine Park. Endemic to Australia from central Queensland south to the Great Australian Bight, and including Tasmania.
Found on exposed rocky shores excepting those with the highest wave action, from shallow subtidal to the littoral zone. They feed on microalgae almost invisible to the naked eye. When exposed they remain stationary, only moving and feeding when covered by the tide.
Shell shape may vary according to shell location in the tidal zone, flatter shells being found in areas where wave action is highest, while taller shells inhabit areas further up the shore. The taller shells are better able to withstand heat and wind dessication. Main predators are the molluscs Dicathais orbita and Tenguella marginalba as well as Oyster Catchers and wrasses that eat the juvenile shells. Shells may reach a maximum length of 65 mm and a height of more than 35 mm.
