A recent study has revealed that the coral reefs close to Pigeon Islands in Trincomalee are facing a threat of extinction.
General Manager of the Maritime Environment Protection Authority Professor Terney Pradeep Kumara stated that this situation was due to an increase in the population of Crown-of-thorns starfish.
He added that unless immediate measures are taken to resolve this issue, the entire reef may be destroyed. Crown-of-thorns starfish are one of the most damaging creatures of tropical coral reefs, particularly Australia’s Great Barrier Reef.
It is stated that they are voracious predators, liquifying coral using digestive juices. A single individual can wipe out large areas in this way. They are almost completely covered in protective venomous spikes capable of causing great pain to humans.
