Tubastraea faulkneri is an encrusting coral that can become massive and strongly convex. The corallites of this species are covered with a porous tissue ( coenosteum ) with a vermicular appearance. The calices have a diameter of 8–10 mm (0.31–0.39 in) and a depth of 5–8 mm (0.20–0.31 in).
Coral is also farmed by scientists for research, by businesses for the live and ornamental coral trade, and by private reef aquarium hobbyists. Coral reef farming involves extracting a part of a coral colony or free-floating larvae from a reef, and growing them in a nursery until outplanting [5] would be successful.
The classification of corals has been discussed for millennia, owing to having similarities to both plants and animals. Aristotle's pupil Theophrastus described the red coral, korallion, in his book on stones, implying it was a mineral, but he described it as a deep-sea plant in his Enquiries on Plants, where he also mentions large stony plants that reveal bright flowers when under water in ...

In the case of stony or hard corals, these polyp conglomerates grow, die, and endlessly repeat the cycle over time, slowly laying the limestone foundation for coral reefs and giving shape to the familiar corals that reside there. Because of this cycle of growth, death, and regeneration among individual polyps, many coral colonies can live for a ...
Elkhorn coral colonies live for centuries. These colonies grow 5–10 cm (2-4 inches) each year, reaching maximum size in 10 to 12 years. [7] Healthy Elkhorn coral can grow up to 13 cm (5 inches) in branch length a year, making them one of the fastest growing coral species.
