Modelia granosa operculum

Modelia granosa


Modelia granosa is a medium to large species of sea snail which has a shell with a pearly interior and a calcareous operculum. It is a marine gastropod mollusc in the family Turbinidae, the turban snails. It is only known to occur in New Zealand. I found these 2 opercula at Lyall Bay (but I have a whole bag of these at home :)

Unfortunately this is neither a turbo smaragdus, nor a cookia sulcata operculum...It's smthng else, an unknown species wich produces an always white, bean-like (oval shaped) operculum...

The operculum is colored in situ but fades when bleached in the surf. I think yours is likely to be 'Turbo sp.' possibly this one
