What Eats Starfish?

On a single day Miguel’s Diving staff witnessed the devouring of two different starfish. In one of the holes that dot the wall at Honeycomb dive site, a couple of triggerfish had eaten most of an up side down Choriaster granulatus. At another dive site a large Triton’s trumpet (Charonia tritonis) had almost completely sucked a common blue starfish (Linckia laevigata) inside its shell. Harlequin shrimp (Hymenocera picta) also feed on starfish, eating it a bite at a time starting with an arm, so as to keep the starfish alive as long as possible.
