Description:

Photo take at -35 ft in a Caribbean reef, this coral forms into massive boulders and sometimes develops into plates. Its polyps are the size of a human thumb and fully extend at night. Great star coral colonies form massive boulders and domes over (1.5 m) in diameter in waters of shallow and moderate depths. In deeper waters, this coral has been observed growing as a plate formation. It is found throughout most reef environments, and is the predominant coral at depths of 20 -40 mt. Wikipedia.
