Townsville (Australia), Jan 06 (ANI): The return of coral-eating Crown of Thorns Starfish has made them a target of a search and destroy mission off Australia's Queensland coast. The Starfish have returned after decades to feast on the Great Barrier Reef, a world heritage and a major tourist attraction. The feasting process begins by the starfish spreading its stomach over the corals and using digestive enzymes to liquefy the coral tissue. To kill the invaders, the scientists suggest injecting them with bile salts. In the Swains Reef at the southern edge of the larger reef system which is under stress due to coral bleaching, a result of climate change according to the scientists, the outbreak took place. Production of extra nutrients in the water has compelled the invasion by the starfish but the scientists are still unknown of the reason behind their return.
