Hey mate hope it is helpful:

Spirobranchus giganteus. These colourful filter feeding worms are sensitive to light. The filaments (little hairy thing's) form an inverted cone and this distinctive shape gives the worms their common name, Christmas Tree worms

Explanation:

Each worm has two tree-like appendages that are used to breathe and to catch meals of plankton floating by. The Christmas tree worms are sedentary, attaching themselves to coral cover that act as their home base. Once attached, they create a calcium carbonate tube that they can then retract into for protection.
