Hi! I hope you learned something while you were reading, bye!
 * Name**: Christmas Tree worm, Spirobranchus Giganteus
 * Anatomy/Appearanc**e: It appears like most tube -building polychaets. It has a tubular, segmented body lined with chaeta, small appendages that aids the worm with it's mobility.
 * Mobility**: As it does not move outside it's tube, this worm does not have any specialized appendages for movement or swimming.
 * Diet**: Christmas Tree Worms feed primarily by filter feeding. They use their brightly-colored radioles to filter microorganisms from the water, witch are then deposited straight into the worms digestive tract.
 * Habitat**: Christmas Tree Worms are wildly distributed throughout the worlds tropical oceans. They have been known to occur from the Caribbean to the Indo-Pacific.
 * adaptations**: As the species is wide spread and relatively common, as far as I know it has none.
 * Life Cycle/Reproduction**: When they reproduce they simply shed their gametes straight into the water where the eggs (and spermatozoa) will become part of the zoo plankton and be carried by the currents.
 * Behavior**:Christmas Tree Worms are solitary animals, and don't really do much.
 * defense/offense**: If danger threatens, the worm can pull it's head down in the blink of an eye.
 * Enemies**: Many fish such as the Butterfly fish try to eat these worms.
