Trochulus hispidus crawling through water

I have taken few photos while a juvenile land snail Trochulus hispidus has been crawling through a very small water pool. Land snails are vulnerable to hyperhydration. But it has spent only about two minutes in the water. Maybe it did not affect its regulation of water much. Hydration is much less known in gastropods than dehydration. Maybe it did it for contact rehydration (“drinking” though the body wall) on that sunny summer day or maybe it has just overcome the pool because it just wanted to go that way. Nobody knows.

I wish you happy and successful new year 2012. I wish you to overcome all difficulties and much more understanding from others.
