Egg Cowry shell

The animal of an adult specimen is jet black scattered with small white spots. Usually, the mantle is fully extended, completely hiding the white shell. Very young and thin specimens have a black mantle ornamented with orange-tipped white bumps.

Other Ovulidae (Mollusca, Gastropoda) are very stange and beautiful. The one I prefer is Calpurnus verrucosus found exclusively on the soft coral Sarcophyton.



Shells of certain cowry species have historically been used as currency in several parts of the world, as well as being used, in the past and present, very extensively in jewellery, and for other decorative and ceremonial purposes. Wiki
