Coral reefs in the ocean are more like sea anemones or sea jellies. Some people compare coral reefs to giant apartment buildings in New York. A number of coral polyps live together, usually a large number in each apartment. Many other animals live on the Coral reef. Some are: sponges, sea urchins, fish, worms, rays, sharks, octopus, lobsters, sea starts, snails etc. All these animals that live in the coral reef work together as a team. Coral polyps work together in teams of thousands. This team work is referred to as symbiosis. This symbiosis helps the coral reef survive in a way as this symbiosis helps kill parasite and Zooxanthellea.
