TRITON'S TRUMPET    Pu

Uncommon on ledges and walls deeper than 20 feet.  They prey upon coral-killing sea stars, but over-collecting has depleted these important snails.  A trumpet is created by removing the upper few whorls.  Attains 19.3 inches, 490mm.  Red Sea to Hawaii, Japan, Pitcairn, Cocos Island, and the Galapagos.  Member of a worldwide species complex.
