In the Serpulacees ( Serpulacea ), the gills are located entirely at the front end of the body; the cilia that coat her cause a current to flow into the water, which supplies food to the mouth opening immediately below it. The head segment is not separated from the mouth segment, as is the case with most other Ringworms, but has grown together with it.
