Résumé
The spatial distribution of juvenile terrestrial snails was studied in clean, symmetrical plastic boxes. Environmental stimuli capable of biasing particular locations in the boxes were reduced to a minimum. Under these conditions, it was found that snails cluster significantly above chance levels. The degree of aggregation is related to the age of the animals, their genetic relationship, and the time of day. Recently hatched snails aggregate less than older animals. Aggregation is greater when the sample population consists of snails hatched from a single clutch of eggs than when it is derived from two different clutches. Aggregation is greater at night than during the diurnal hours. The sensory basis of the phenomenon is considered to be olfactory.
