Christmas Tree Worms

Christmas Tree Worms (Scientific name: Spirobranchus Giganteus) are small, tube-building  worms belonging to the family Serpulidae. These attractive corals come in a variety of colors ranging from yellow and orange to blue and white. They are widely distributed throughout the world’s tropical oceans. The worm’s multicolored spirals actually are highly derived respiratory structures. It lacks specialized appendages for movement or swimming and does not move outside it’s tube. They have two beautiful crowns which give them Christmas tree appearance and hence they got their name. These crowns are specialized mouth appendages of the worm. They are very sensitive to disturbances. Even a shadow causes an instant reaction. It’s tube is it’s home.
