Description

Broad Banded Water Snake Belly

Size

It is typically 20-30 in (61-76 cm) in length.

Color and Appearance

Juvenile Broad Banded Water Snake

The stocky body of the snake bears an irregular pattern of broad black bands that fade to shades of orange or yellow and brown. Often a faint dark line runs diagonally from the eye past the corner mouth. The yellow belly is boldly black markings. The head is only slightly wider than the neck. It has keeled scales that are arranged in rows of 21-27 near the midbody. It has divided anal scales and round pupils. The juveniles are more brightly colored than the adults.

Are They Dangerous to Humans

When the snake feels threatened and cannot escape, it flattens its head and neck and vigorously tries to defend itself. Though the snake is non-venomous, it can viciously bite if harassed. It also secretes a strong-smelling musk from glands located at the base of its tail.
