Miliaris cowrie
Erosaria miliaris
Family Cypraeidae
updated Oct 2016

Where seen? This pretty cowrie with a spotted shell is commonly seen on our Northern shores, under and on rocks or on sandy and silty areas among seagrass. It was previously known as Cypraea miiliaris.

Features:
2.5-4cm, up to 5cm. Shell is pear-shaped, beige to light brown with white spots all over it and a broad white margin around the base. It has a very 'hairy' looking mantle. The underside is completely white and the 'teeth' are not coloured.

They are often found as a pair of male and female. If you find one, the other is usually not far away!

Sometimes mistaken for a sea slug. When the shell is completely covered in its mantle, it is sometimes mistaken for a hairy sea slug. Here's how to tell apart hairy slugs and snails more on how to tell apart slugs and animals that look like slugs.

Status and threats: Like other creatures of the intertidal zone, cowries are affected by human activities such as reclamation and pollution. Trampling by careless visitors and over-collection can also have an impact on local populations.
