Coral Biology

The basic living unit of the class Anthozoa (further subdivided into subclass Hexacorallia, which includes stony corals, and subclass Octocorallia, which includes soft corals) is the polyp. Polyps can occur either singularly, as in the case of anenomes, or can form colonies, as they do in stony and soft corals.

This section is dedicated to providing the essentials of coral biology focusing on the structure and function of these organisms.
