How are coral polyps formed?
Reefs form when polyps secrete skeletons of calcium carbonate (CaCO3). Most stony corals have very small polyps, averaging 1 to 3 millimeters in diameter, but entire colonies can grow very large and weigh several tons.
What are called polyps?

What is coral polyp made of?
Most structures that we call “coral” are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps. Each soft-bodied polyp—most no thicker than a nickel—secretes a hard outer skeleton of limestone (calcium carbonate) that attaches either to rock or the dead skeletons of other polyps.
Do corals live forever?
This is how a single coral can, at least theoretically, live forever. Individual polyps will die but the colony will go on growing indefinitely provided that the environmental conditions continue to support its survival. Coral have been found that are more than 4,000 years old.

What are Ricordea corals?
Ricordea make up the only genus in the Ricordeidae family of corallimorphs. Ricordea corals have a small, round body with short club or berry-shaped tentacles.
What are the characteristics of Ricordea?
Ricordea make up the only genus in the Ricordeidae family of corallimorphs. Ricordea corals have a small, round body with short club or berry-shaped tentacles. The basal portion of the coral contains a flat disk that functions as a foot supporting the oral disk.
Where can I buy Ricordea?
Foxy Saltwater Tropicals is proud to offer a great variety of hand collected Ricordea from the warm waters of the Florid a Keys. In fact the varieties we sell are often referred to as Florida Ricordea. Ricordea can also be found in the Pacific and those varieties are referred to as Yuma Ricordea. Ricordea go by various names.
Where is the mouth on a Ricordea coral?
The basal portion of the coral contains a flat disk that functions as a foot supporting the oral disk. As with other corals, you’ll find the mouth in the center (sometimes more than one if the Ricordea is in the process of splitting).
