Diet of olives: Oliva tigridella Duclos, 1835 in Queensland

Abstract

Field observations of Oliva tigridella in Queensland revealed a diet of small gastropods, bivalves, echinoids and holothurians. Foraging animals were observed carrying prey attached to the rear of the foot. Up to seven prey items were recorded on the foot. Analysis of gut co ntents showed a high frequency of holothurian spicules although these were rare amongst items found on the foot. This study reveals a previously unrecorded catholic diet of olives although small gastropods and bivalves are important components.
