The coral consists of a central polyp surrounded by a hard exoskeleton. The polyp is a living creature that only measures a few millimetres in diameter. It is a cylindrical vase-shaped creature that has tiny tentacles at one end. These appendages pass food into the mouth of the polyp. Poly...
7. If you find a broken piece of coral on thebeach, you can see its hard shell, which is actually ananimalcalled a polyp. It is the cluster of these polyps growing together that gives coral reefs their shape. 8. Some coral reefs are more biodiverse than others. The array of marine s...
Of the 6000 or more species in the world today, about 3000 are stony corals. Another 1200 are horny gorgonians and about 800 are soft corals. Coral animals are made up of a central polyp with a skeleton growing around it. Each individual coral polyp body is shaped like a tube with one ...
5. Coral polyps – typically no bigger than a grain of rice – are the basic building blocks of the Great Barrier Reef. These tiny colonial animals contain a symbiotic algae in their cells. As the algae photosynthesise, each fuelled polyp secretes a “house” of calcium carbonate. One house...
