Coral polyps are tiny animals that build protective calcium carbonate skeletons. Coral polyps create the basic structure of coral reefs with the help of single-celled algae. Coral reefs can be seen from space, but they are made by one of the worldâs simplest animals - some no bigger than the head of a pin. They are able do this because of their symbiotic relation with single-celled algae.
