Sense Organs and Behaviour

Abstract

Sense organs that respond to touch and to chemical stimuli play an important role in the behaviour of nematodes, as most of these animals live in the dark in soil, in mud, or in the organs and tissues of other organisms. A very small number of nematodes have structures which may play a role in sensitivity to light. Unfortunately very little physiological work has been done on nematode sense organs and in most cases their function has had to be assumed from their location on the body of the nematode, or from their structure.
