ABSTRACT
Nematodes respond to a wide variety of stimuli. These include chemical stimuli (chemoreception), touch (mechanoreception), temperature (thermoreception) and, in some cases, light (photoreception). Given the diverse array of environments occupied by nematodes it is not surprising to find that different nematodes utilise each of these senses to varying degrees. Those that are heavily dependent on one particular source of stimulus may have some sense organs developed or adapted to enhance reception of this stimulus. Detailed reviews on both the structure (McLaren, 1976a, 1976b; Wright, 1980) and function (Bargmann and Mori, 1997; Driscoll and Kaplan, 1997) of nematode sense organs have been published. Here, an attempt is made to cover both these areas and link the two together.
