Reef Villain Redeemed

The crown-of-thorns starfish, notorious for destroying coral reefs, may have been unfairly cast as the villain. Australian researchers discovered that, in small numbers, these prickly predators can actually improve reef biodiversity by making room for slower-growing corals. Nearly three-quarters of observed feeding events left living coral behind. Encouraging news for reef conservation, including Antigua’s own restoration efforts, which have planted thousands of corals this year. Apparently, even the ocean’s most unpopular dinner guest has a useful role to play. Just don’t invite the entire family.
