Transport, Excretion, Nervous System

The nervous system in kamptozoa consists of a single large ganglion in between the mouth and the anus from which individual nerves reach out to the whole body. There are no special respiratory organs; instead gaseous exchange takes place over the surface of the body. The water current generated by the animal carries feces away from the mouth out through the central space in such a way that it does not contaminate the food bearing cilia.
