The Organ pipe coral (Tubipora musica) is an alcyonarian coral native to the waters of the Indian Ocean and the central and western regions of the Pacific Ocean. It is the only known species of the genus Tubipora. This species is a soft coral but with a unique, hard skeleton of calcium carbonate that contains many organ pipe-like tubes. On each tube is a series of polyps which each have eight feather-like tentacles. These tentacles are usually extended during the day, but will swiftly withdraw with any sort of disturbance. The skeleton is a bright red color, but is typically obscured by the numerous polyps, which are green or gray in color. In size, colonies can reach up to a meter across, while the individual polyps are typically less than 3 mm wide and a few mm long. They are restricted to shallow waters and tend to live in sheltered areas. They eat plankton. They are close relatives to other soft coral and sea fans.
Famous quotes containing the words organ, pipe and/or coral:
“What we commonly call man, the eating, drinking, planting, counting man, does not, as we know him, represent himself, but misrepresents himself. Him we do not respect, but the soul, whose organ he is, would he let it appear through his action, would make our knees bend.”
—Ralph Waldo Emerson (18031882)
“If you would get money as a writer or lecturer, you must be popular, which is to go down perpendicularly.... You are paid for being something less than a man. The state does not commonly reward a genius any more wisely. Even the poet laureate would rather not have to celebrate the accidents of royalty. He must be bribed with a pipe of wine; and perhaps another poet is called away from his muse to gauge that very pipe.”
—Henry David Thoreau (18171862)
“The cities are the principal home and seat of the human group. They are the coral colony for Man, the collective being.”
—Alfred Döblin (18781957)
