Water Snake
The head of water snakes is narrow and pointed, in contrast to the broad, triangular head of Burmese pythons.
Brown water snakes are light tan with darker brown squares on the back, giving a checkerboard appearance (as opposed to the puzzle piece appearance of Burmese pythons). The belly is light colored with darker blotches and half moon shapes. Brown water snakes can grow to 4.5 feet in length and are found throughout the state except for the Keys.
Banded water snakes are heavy-bodied snakes that can grow 2-4 feet in length. They have dark brown or black crossbands down the back that alternate with lighter tan or reddish crossbands. The belly is yellow with worm-like black or red markings and a dark line runs diagonally through the eye.
