Balanoglossus

a genus of animals of the Enterop-neusta class, Hemichorda subphylum. The body (up to 2.5 m long) is divided into the snout, the collar, and the body proper. In the USSR there is one species (up to 9 cm long), found in the Sea of Japan. It lives in the mud and sand of coastal sea waters. Representatives of other genera of the Enteropneusta class are also often called Balanoglossus, for example, the Saccoglossus mereschkowskii (up to 10 cm long), which lives in the White and Barents seas.

Molecular sequence data suggest that the harrimaniid worms are more closely related to the colonial class Pterobranchia (including the genera Rhabdopleura and Cephalodiscus), which also have paired protocoel ducts and pores, than they are to the ptychoderid worms (Balanoglossus and Ptychodera) (Cameron et al., 2000).
