That's weird. I thought they laid their eggs in the water and that's where they hatch... I never knew that we live water births. I remember we had a reptile exhibition at our high school once 20+ years ago. The bloke got this anaconda out of one of those big bags they carry them in. Scared the living fuck out of me.
Interesting fact, some of the really big snakes have legs, but their legs are so small and useless, they are embedded within their body as these creatures have evolved. Eventually, these legs will disappear.
