Water Snakes

At times, kids (especially boys) are genius for finding something very interesting and odd. 

Without a boy from Germany, I don't think I've noticed the small water snakes living in Malom Lake (Malom-tó) in Tapolca... It appears there are at least two types of snakes there, however, I know nothing about them.

To be honest, this was my first time seeing snakes living in water...
