Description

The shell of Zoila thersites can reach a length of 56–116 millimetres (2.2–4.6 in). This quite rare shell is oval, with a narrow aperture. Dorsum is distinctly arched and the base is pale brown and almost flat. Outer and inner lips have fine teeth. Surface of the shell is smooth and shiny, black or pale brown, more or less densely covered with large irregular dark brown spots. Mantle and foot are very developed. The mantle covers almost entirely the shells. This species lays eggs capsules with a single fertilized egg. When it hatches, the larva feeds on the so-called nurse eggs.

Distribution and habitat

This endemic species occurs in the sea along Southern Australia. These beautiful cowries live from the intertidal zone to the deep reef, but they prefer shallow waters, near the intertidal rocky seabed. At dawn or dusk they start to prey on sponges, foraminifera, algae and small crustaceans.
