1. CHRISTMAS TREE WORM By Seyvon

2. SPIROBRANCHUS GIGANTEUS I am Spirobranchus Giganteus but you may know me better as the “Christmas Tree Worm” and I am 1-1.5 inches in span.

3. CHRISTMAS TREE WORM HABITAT MAP

4. MY HOME I live on tropical coral reefs and resemble a fluffy fir tree adorned with colored ornaments.

5. CHRISTMAS TREE WORM RETRACKING

6. WHY THEY RETRACK I am very shy and will pull into my tube instantly when I am threatened.

7. REVERSE RETRACKING

8. MY FAMILY I am related to the “Polychaete Family” living in tropical waters. ScrpulidaePhyllodocidaeSternaspidaeAmphinomidaeNereididae

9. HOW I FEED I am a Polychaete Ciliary feeder which means that I feed using radioles.

10. THREATS TO SPECIES I am NOT under a threat of extinction but I am losing my habitat. My hard coral reef homes are dying out and the changing of water temperatures are a problem as well. A lot of my family are also being used as pets in aquariums.

11. REPRODUCTION The females and males release the eggs and sperm into the water column where fertilization happens.

12. PREDATORS One of the known predators are the “Butterfly Fish”

13. COLORS THEY COME IN

14. INTERESTING FACT ABOUT THEM By counting growth rings on the coral, scientist have figured out that a worm can be from 10 to 40 years old.
