Quick Answer

Full Answer

Coral are tiny, soft-bodied animals. They somewhat resemble upended jellyfish, with tentacles surrounding their only orifice, which serves as both anus and mouth. The coral reef is not the animal itself but a structure built by many coral together. The creatures take in calcium from seawater and convert it into a protective coating that they secrete around themselves. The resemblance to jellyfish is not a coincidence; coral is related to box jellies and the true jellyfish. Some cnidarians switch between a stationary, coral-like form and a free-swimming, jellyfish form over the course of their life cycle.
