Wandering cowrie
Cypraea errones
Family Cypraeidae
updated Jan 11

if you learn only 3 things about them ...
Cowries are often well camouflaged. Look carefully for them.
Their shells are highly prized, thus cowries are threatened by over-collection.
Don't rip off a cowrie from a stone! It might be a mother cowrie protecting her eggs.

Where seen? This little cowrie is commonly seen on our Northern shores usually under stones, but sometimes crawling about in the open. Sometimes also seen on our Southern shores among coral rubble.

Features: 2-3cm.
Shell cylindrical. Upperside variable patterns with one or two brown spots at the front tip of the shell, sometimes no spots. Underside without coloured 'teeth'.

Sometimes confused with the Ovum cowrie (Cypraea ovum) which is similar but is pear-shaped, does not have spots at the front end of the shell and has 'teeth' that are tinged yellow or orange. Here's more on how to tell apart Wandering and Ovum cowries.

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

Leave cowries alone: Mother wandering cowries often lay their eggs under stones and then stay over their eggs. So if you see a cowrie under a stone, please don't rip it off. You might inadvertently separate a mother from her eggs!
