Abstract The influence of light upon behavior of Biomphalaria glabrata was investigated in snails submitted for 48 h to one of the following regimes: normal light cycle, continuous darkness, continuous light. Time-lapse cinematography was used to provide data about snail locomotor activity in response to (a) continuous light or darkness; (b) light or dark phases; (c) light transitions. Snails were significantly less active under continuous light than under continuous or intermittent darkness. Under the normal light cycle, the activity rate was significantly higher in the dark than in the light. Changes from light to dark corresponded to increases in the activity rate which persisted long afterwards. No significant variation in activity occurred upon changes from dark to light.
