I went for a snorkeling swim to test a camera (its what I do) and to visit my water friends, fishes and reptiles.
So I met this young fellow which, like 99% of all watersnakes, shows neither fear nor agression. He remained on my palm watching me and the camera with curiosity until it became too warm for him and he slithered back into the water.
Im certain well meet again, and many times! And when he grows big, hell probably behave just like here. They remember well!
