The early Hawaiians used the Triton�s Trumpet (Charonia tritonis) as a blowing shell. One of the largest mollusks found in Hawaii, the Triton�s Trumpet is one of the few predators on the Crown-of-Thorns sea star (Acanthaster pianci).

This Triton's Trumpet is lying on its back and was photographed in about 40 feet of water off the south Kohala Coast near Puako Beach on the Big Island of Hawaii.
