Brown Watersnake

Nerodia taxispilota

Reptile

A large nonvenomous watersnake of Florida rivers, lakes, swamps, and tree-lined shorelines.

Brown Watersnakes occur in northern and central Florida near slow rivers, lakes, swamps, and reservoirs. They often bask on branches over water and drop quickly when disturbed.

Their heavy body and blocky markings lead to confusion with cottonmouths. Observation from a distance protects people and this native fish predator.
