Latin is so interesting……the Latin name for the Christmas Tree Worm is Spirobranchus Giganteus. Spirobranchus is so fitting for these little guys. Look at the cool spirals on this fellow!
These worms are found on hard corals and have a tube like body that goes down into the coral and two crowns that protrude from its body and “sit” on the coral. The crowns are used for respiration and to catch food. When startled, the crowns get retracted into the tubes. They come in a myriad of colours and are fun to go BOO! at.
