Abstract: 1. Littorina planaxis show a correlation between size and rate of water loss, the large animals losing more slowly than the small ones. 2. Decreasing surface/volume ration with increasing size probably explains this finding. 3. Clustured snails dessicate at a slower rate than single individuals attached by mucus, which in turn dessicate more slowly than those with no mucus attachment, in a dessicator, in the laboratory and under natural conditions. 4. The tolerance for dessication was found to be quite high. Snails dessicated in a nuatural environment lost approximately 70% of their total water and survived.
