Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms.Thousands of species of corals have been discovered; some live in warm, shallow, tropical seas and others in the cold, dark depths of the ocean. At their base is a hard, protective limestone skeleton called a calicle, which forms the structure of coral reefs. Coral reefs are formed as individual coral colonies build hard skeletons (made of calcium carbonate) that support their soft living polyps. Coral isn’t actually a plant – it’s more of an animal!

Coral polyps are tiny, soft-bodied organisms related to sea anemones and jellyfish. This small, colorful octopus can be found in tide pools and coral reefs in the Pacific and Indian oceans. Zooxanthellae are single-celled dinoflagellates that conduct photosynthesis.The zooxanthellae use the waste products of the coral during photosynthesis, and the coral can use the nutrients provided by the zooxanthellae during photosynthesis. The polyps surround themselves with layers of hard minerals. Coral reefs are animals, which means that, unlike plants, they are unable to make their own food. Living in warm shallow waters often near coral reefs in the Western Atlantic, from Florida to Brazil, the Caribbean reef shark (Carcharhinus perezi) is the most abundant shark in the Caribbean. The corals benefit, in turn, as the algae produce oxygen, remove wastes, and supply the organic products of photosynthesis that corals need to grow, thrive, and build up the reef. They actually share plenty in common with various animals of the deep, such as sea anemones. Coral reefs are large underwater structures composed of the skeletons of coral, which are marine invertebrate animals. Unlike rocky reefs, where the reef structure is created by geological processes, the reef structure on coral reefs is created by biological processes – the growth and death of reef-building corals, sponges, and other immobile marine animals. For example, due to their proximity to the shoreline, the fringing reefs have a significant association with both sea grass and mangrove depending on the position of the tide. There are ahermatypic corals, sponges, many invertebrates, fish, mammals and seaweeds. Shoal grass is the most grass-like looking out of the other types of sea grass. Residing within the coral's tissues, the microscopic algae are well protected and make use of the coral's metabolic waste products for photosynthesis, the process by which plants make their own food.
