How do Christmas tree worms survive?
These Christmas tree-like crowns are composed of radioles, or hair-like appendages radiating from the worm’s central spine. These appendages are used for respiration and to catch dinner, which typically consists of microscopic plants, or phytoplankton, floating in the water.
How does a Christmas tree worm produce its outer tube?
The sperms fuse with the eggs and fertilization occurs. Fertilized eggs develop into larvae that live as plankton for 9-12 days and then settle on coral, where they produce a mucus tube which develops into a calcareous tube (Kennedy, 2015). The life span of Spirobranchus giganteus is over 30 years.
What do Christmas tree worms decompose?
Christmas tree worms eat primarily zooplankton, phytoplankton, and organic matter. Because they consume organic matter, they are considered to be decomposers.

Once settled down, a Christmas tree worm can live upwards of 30 years! (Though 10-20 is more common.)
Do Christmas tree worms reproduce sexually or asexually?
Many invertebrates reproduce asexually, but there are male and female Christmas tree worms. They are broadcast spawners, meaning they fire their gametes into the water, where they float around until a sperm fertilizes an egg. While they typically live in coral, these worms occasionally burrow into giant clams.
