Cephalodiscida is one of two orders in the class Pterobranchia, which are small, worm-shaped animals. Members belong to the hemichordates.[1][2] Species in this order are sessile, living in clear water and secrete tubes on the ocean floor.[3]

The order is a small one, with only two known families, each containing a single extant genus. The validity of the family Atubaridae, who has only a sole member, is regarded as questionable.[4]
