Coral is the skeleton of many small marine organisms that comprise a colony. These organisms are polyps, each a few millimeters in size.

When a new polyp is born, it attaches its skeleton to the colony and thus expands it. In coral colonies, along with the polyps, some single-celled algae coexist, which photosynthesize and supply food to the polyps, and at the same time secrete pigments that color the colonies, i.e. the corals. Corals have a hardness of 3.5 and a specific weight of 2.6. The colors of corals are pink-red, beige, and white.
