Serpulid Worms (Spirorbids)
Contributed by Dr. Bonnie Becker
Where found: In small, tightly-coiled, calcareous tubes (openings with diameter less than 1mm) on immersed small, round boulders.
Interesting facts: Tiny red gills stick out of the tubes, which will disappear if the rock is touched.
Adaptations: Living in calcareous tubes protects the worm from predation and desiccation.
Food: They are filter feeders, gathering food particles from the water.
Life history: These animals are hermaphrodites. They brood their young.
Phylum: Annelida (segmented worms)
Class: Polychaeta (Bristle worms, Fan worms, Clam worms, etc.)
