“ 'The debate is over. This latest research demonstrates that more decisive action to cut chemical fertilizer is urgently needed to prevent unprecedented and on-going outbreaks of Crown of Thorns starfish, which are in turn converting the Great Barrier Reef into rubble,' WWF-Australia spokesperson Nick Heath said in a statement."
"According to the study, the starfish in its larval stage feeds on plankton, populations of which surge when fertilizer runoff floods the coastal ocean waters with nutrients. So plentiful plankton can lead to swarms of hungry starfish."
"The starfish consume the corals by climbing onto them, thrusting out their stomachs, and bathing the coral in digestive enzymes, which liquefy it for ingestion. Adult crown-of-thorns starfish, ranging in size from 9 to 18 inches in diameter and with up to 21 arms, can eat nearly a square foot of coral each in a day." 10-12
