The crown-of-thorns (Acanthaster planci) is a starfish native to coral reefs in the Indo-Pacific region.

The starfish A. planci eating a coral

Generally, on healthy coral reefs, this coral-eating starfish plays a special role, as it tends to feed on the fastest growing corals such as stag-horns and plate corals, allowing slower growing coral species to form colonies.

This helps increase coral diversity.

However, outbreaks of this animal pose one of the most significant threats to the Coral Reef.


To help Pom Pom coral reef, the conservation team regularly remove this starfish and then burial ashore or drying out in the sun.

Removing the crown-of-thorns starfish is not an easy job, and we have got the scars to prove it. A spine to the hand does not feel good and tends to bleed profusely.

Sharks’ duty is to keep populations of other fish healthy and in proper proportion for their ecosystem.….
