Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The polyps are white and each one has eight pinnate tentacles which give the colony a feathery appearance when they are extended. Distribution This coral is found on the west coast of Britain and Ireland, north to western Scotland and south to the Bay of Biscay. It is quite localised but may be abundant in places. It is also found on the East Coast of United Arab Emirates (Gulf of Oman - Indian Ocean) on wreck: Inshcape-2 opposite to Khor Fakkan, Khurr-Fakkan City.
