The cone-like shape of double helix and magnificent plumage of this serpulid tube-dwelling worm has earned the name "Christmas tree worm" among divers and aquarists. Among the sedentary polychaete worm, is admired and readily identifiable, albeit small (ie less than 1 1 / 2 inches or 3.8 cm in size). The tentacles of color are used for food on the passage of suspended particulates and breathing. Much of the worm is anchored in its burrow, boring a hole in a limestone coral alive.These worms are very sensitive to disturbance, and therefore are difficult to address without at least one episode of an almost immediate withdrawal of the lair. Touching the tentacles, or even the passage of a shadow can cause a defensive reaction. Fortunately not remain hidden for too long, usually less than a minute before slowly emerging from the hole to see the tentacles in all its splendor.

Yes this is something you will always see underwater when you're diving. It's nice to play with these creatures; try to touch it and it will retract into its shell so fast you will think the whole thing is made up of muscle.
Very nice :-)
Is that worm? I hate worm, but this one's beautiful.
I think this is beautiful. Worm or no worm. The beauty of aquatic living things. *^_~*
