The development of nematode behaviour: stage-specific behaviour in Panagrellus redivivus

Larvae of the free-living nematode Panagrellus redivivus differ from adults in their attraction to bacteria. Under osmotic stress larvae coil, while adults do not. Larvae do not travel as far, but undergo more looping, turning, and reversal activity than do normal adults. A behavioural mutant, corkscrew, with primary expression in adults, shows differences in behaviour at each stage of the life cycle.
