Global warming can have a devastating effect on coral reefs. As sea temperature increases, the special symbiotic relationship breaks down between corals and tiny marine algae (zooxanthellae), that live inside coral tissue and give corals much of their colour. Without the zooxanthellae, the tissue of the coral animal appears transparent and the coral's bright white skeleton is revealed. Corals begin to starve once they bleach. Bleached corals often die if the stress persists. Coral reefs that have high rates of coral death following bleaching can take many years or decades to recover.
