Brain corals are found in shallow warm-water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or flower animals. The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height. Brain corals extend their tentacles to catch food at night. During the day, they use their tentacles for protection by wrapping them over the grooves on their surface. The surface is hard and offers good protection against fish or hurricanes.
Corals are marine organisms of class Anthozoa (Kingdom Animalia, Phylum Cnidaria, Class Anthozoa) that typically live in large colonies of identical individuals. They are important reef builders in tropical seas, and are secretors of calcium carbonate (CaCO3) that forms their hard skeleton.nthozoans do not have a medusa stage in their development as do other cnidarians. Rather, they release sperm and eggs that form a planula that attaches to a surface on which they grow. A coral head contains thousands of genetically identical polyps, each typically a few millimeters in diameter.
