Family Serpulidae: Calcareous Tubeworms. Sometimes further divided into worms with spiral tubes (Spirorbidae) and straight (Serpulidae). Produce white, calcareous tubes, often with longitudinal ridges, thickenings, spines. Shape, size of cover (operculum) often useful in determining species. Includes genera: Serpula, Spirobranchus, Protula 

Some serpulids are tiny, down to barely noticeable with the naked eye. Here are some calcium tube dwelling ones on a relatively large Sea Squirt in N. Sulawesi. Smaller than pinhead size. 

Genus Filograna:

Filograna elatensis, Ben Eliahu & Dafni 1980. A Serpulid with distinctive reddish pinnate tentacles. Red Sea to Indonesia, S. Japan, Australia and New Guinea. N. Sulawesi.
