Tritons: Family Cymatiidae
Cymatiidae is a family of large sea snails in the superfamily Tonnoidea and the order Littorinimorpha. Members of this family are predators. The main shells of this family I've collected are known as Hairy Tritons, Cymatium (Monoplex) pileare (Linnaeus, 1758). The Hairy Triton is a relatively common tropical western Atlantic species that is present also in the tropical Indian and Pacific oceans, including Polynesia and Hawaii.
