- Balanoglossus lives in burrows in the intertidal sandy areas.
- Its body is long cylindrical.
- In its pharynx 'U' shaped gills are present with increase in its age the number of gills will increase in number.
- Each gill has two lobes.
- These two lobes are separated by tongue bar. This tongue bar is hollow.

- The gills are supplied with blood capillaries.
- These gills open out through gill slits.
- The water from pharynx will enter into the gills.
