Closed Brain Coral

Description

The textures and colors of coral are unreal! As incredible as the whole tropical reefscape is, one can just as easily get lost in the details. Much of a coral's color comes from microscopic algae called zooxanthellae that live in its tissues and are also its main source of food. When the water is too warm, corals expel the algae and turn completely white. A bleached coral is not dead.
