Abstract

Quantitative evidence on predation rates on soft corals is presented for the first time. These measured predation rates were low. Less than 1% of the soft coral colonies present in mapped areas at Heron Island and Beaver Reefs had bite marks. Evidence suggests that over 51% of these bite marks were more than two months old. Predators included the mollusc Ovula ovum and two species of chaetodontid fishes that have not been recorded before as feeding on soft corals.
