Abstract

Summary

Measurement of rheotactic responses of indicated that stream velocities above 35 cm/sec prevent any degree of upstream progression, but that below this flow rate snails show increasing ability for positive rheotactic orientation movement. When chemical attractants were applied, increased its rate of upstream migration. Persistence of increased progression rates after the cessation of chemical stimulation suggests a behavioral pattern similar to that known to exist in insects subjected to pheromonal stimulation.
