Sabellida
Sabellida is an order of annelid worms in the class Polychaeta. They are filter feeders with no buccal organ. The prostomium is fused with the peristomium and bears a ring of feathery feeding tentacles. They live in parchment-like tubes made of particles from their environment such as sand and shell fragments cemented together with mucus.
Members of the suborder include the feather duster worms and serpulid worms. Among the species are the giant feather duster worm, the peacock worm, the European fan worm and the Christmas tree worm.
