"Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae – these are what give the coral their colour," said Head.
The rich colors are caused by the presence of minute algae called zooxanthellae that live symbiotically in the coral tissues.

Reef-building corals contain plant-like organisms called zooxanthellae that live symbiotically within their tissue.
Corals have symbiotic algae, called zooxanthellae, living within their body tissues.
Coral bleaching, satellite observations, and coral reef protection
The animal, a tiny polyp, shelters a tinier plant (an algae called zooxanthellae), which returns the favor by sharing the energy it produces through photosynthesis with its host.
Within the tissue of most reef-building corals live symbiotic small algae called zooxanthellae (pronounced zo-zan-thel-ee) that are capable of photosynthesis (changing sunlight energy into food).
Algae called zooxanthellae live within the coral, give it its brilliant reds, oranges and browns and through photosynthesis provide 98 percent of the coral's food.
National Geographic explains, "Solar rays nourish essential, algae-like organisms called zooxanthellae, which live symbiotically in the jellies' tissues and provide their hosts with energy as a byproduct of their photosynthesis."
"Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour," said
On our current trajectory, the pH will continue to decline past the point where corals and the algae species known as zooxanthellae that live symbiotically with the corals can work together to form expelled coral skeletons into calcium carbonate - the engine of coral reef growth.

"Corals live in a symbiotic alliance with tiny algae called zooxanthellae. Thanks to photosynthesis, the algae capture sunlight and use it to turn carbon dioxide into organic carbon, with oxygen as a waste product. of the process. The coral then uses the oxygen in its own metabolic cycle."
