White syndrome destroys the coral�s tissue completely turning these colourful organisms into inert skeletons of calcium carbonate.

Los arrecifes coralinos son los ecosistemas marinos más biodiversos del planeta. Aunque solo cubren el 0,1% de la superficie de los océanos, albergan cerca de un tercio de todas las especies marinas conocidas, una diversidad solamente comparable con la de los bosques tropicales.

Los corales son pequeños animales, mayormente coloniales y con forma de anémona. Existen dos grupos principales, los corales duros y los corales suaves.
