Fat corals fare best as climate changes
Corals don't live solitary lives. Their existence depends on one-celled algae called zooxanthellae that take up residence inside those ornate structures. The tiny algae give corals oxygen and other nutrients (as well as their beautiful colors), and in return, the corals give the algae carbon dioxide—a symbiotic arrangement. With global waters warming and increasing in acidity, it's well known coral reefs are in trouble. Warmer waters cause corals to expel the life-enabling symbiotic algae that they normally pair with, triggering a suicidal process referred to as coral bleaching.
