Abstract A study was made on I. exustus to observe the survival and osmotic regulation following transfer of snails from freshwater to different salt concentrations. The lethal salinity was found at 0.5% salt concentration. It was observed that there was loss of chloride ions in distilled water whereas the snails gained chloride in different salt concentrations. The gain of chloride ions was found to increase with increasing salt concentration. The body weight changes in snails showed that there was increase in weight when placed in distilled water. In tapwater they showed little fluctuation, whereas weights decreased with increasing concentration of salt, thus suggesting that in hypotonic media the snails could regulate their water content, but in hypertonic media they lost considerable weight due to loss of water.
