Polished Nerite (Nerita polita)


Nerita polita is probably the most widely distributed nerite, occurring along tropical and sub-tropical shorelines from southern Africa, through the Indian Ocean to islands of the central Pacific. In Australia, it is found from North West Cape in Western Australia to northern New South Wales. It often buries itself in sand, surfacing at low tide to graze on rocks. On some beaches, the receding tide heralds a mass emergence of these glossy shells.



Geerat Vermeij (1984) placed Nerita polita in the subgenus Linnerita with three other less well-defined species. The subgenus is characterised by the granulate/wrinkled rim on the operculum.

And let us not forget how these little beasties have come to use use different microniches (at least in Tsv) to appear to "co-habit" with those most closely related all on the same rock! Nice pics by the way...

Pestie (I'm taking a punt on ID!), somewhere in my filing cabinet I've got a paper that describes just that ...
