Nerodia - from the Latin word neros, meaning swimming thing and dia, meaning across or over
sipedon - si, the Latin for "waves" and pedon for "ground", referring to the fact that this snake moves as well on the land as it does in the water (waves). It may also refer to the Latin paedidus, meaning stinky, referring to the smell that the snake produces
True to its common name, the northern water snake inhabits a variety of aquatic habitats including lakes, ponds, and rivers. Water snakes of the genus Nerodia are generally stout, short-bodied and larger than their cousins of the genus Regina.
