In spite of its hard skeleton, the organ-pipe coral is actually a type of soft coral, closely related to sea fans. It is the only known species of its genus. Its bright-red skeleton, which is made of calcium carbonate, contains many organ-pipe-like tubes (hence the name). In each tube is a series of polyps, each of which has eight feather- or flower-like tentacles, which are usually extended during the day. T. musica colonies can reach up to a meter across, but individual polyps are typically less than 3mm wide and only a few millimeters long.
This species typically occurs in shallow reef areas, possibly to 12m or more, and is found on exposed reef locations, and reef flats.
Spotted this very attractive coral in 24m of water at Dayang Beach during a day dive.
