Christmas tree worms(Spirobranchus giganteus): Beautiful tube-building polychaete worms Spirobranchus giganteus, commonly known as Christmas tree worms, are tube-building polychaete worms belonging to the family Serpulidae. Spirobranchus giganteus is commonly found embedded in entire heads of massive corals, such as stony corals like Porites and brain corals. As sedentary inhabitants of coral reefs, Christmas tree worms feed primarily by filter feeding. They use their brightly colored radioles to filter microorganisms from the water, which are then deposited straight into the worm's digestive tract.
