Tiny plant cells, known as dinoflagellates, that live within
coral tissue can help to regulate the osmotic pressure in corals to better cope
with a highly saline environment. KAUST researchers suggest this may be one of
the secrets of corals from the Red Sea and Persian/Arabian Gulf, which are
extremely tolerant of heat in extraordinarily salty waters.
