Corals are Animals, Fascinating the creature of mother Nature

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality. Coral bleaching is of particular concern today as our climate changes and temperatures rise.
