Coral Bleaching. There are roughly 400 species of corals on the Great Barrier Reef, and most of them have a symbiotic relationship with zooxanthellae algae – a microscopic plant that lives inside the tissue of the coral in exchange for providing the coral with up to 90% of its energy requirements. Like most plants.
