Neverita duplicata
Species of mollusc
Neverita duplicata, common name the shark eye, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails.[1]
In 2006, a paper was published which made it clear that a second, very similar, species with a smaller range of distribution also lives in part of the range inhabited by Neverita duplicata. The second species had previously been considered to be simply a form of N. duplicata, but it is now recognized as Neverita delessertiana.[2]
