Christmas tree worm
Christmas tree worm (Spirobranchus giganteus). This polychaete worm lives in a tube attached to coral or rock, and extends long radioles (yellow) into the water to trap passing food particles. At the slightest hint of danger these are withdrawn rapidly into the tube. This worm is found in tropical regions throughout the world. Photographed off Sulawesi, Indonesia.
