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
pear-shaped, with 'teeth'
that are tinged yellow or orange. It does
not have spots at the front end of the shell.
Sometimes
confused with the Wandering
cowrie (Cypraea errones) which is similar but is cylindrical
in shape. It does not have coloured 'teeth' and has a brown spot or
spots at the front end of the shell. 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!
