To identify the cottonmouth snake, which is venomous, look at the tips members of this snake group provided:


  • notice the jagged pattern the cottonmouth's back (although in some cases the color may be too dark to notice the pattern)
  •  dots in the center
  • black stripes around the eye
  •  tails often same color as body ( juveniles have greenish or yellow tails). Not the best identifier for adults.
  • Body shape, triangular in cross section.
  • Head - angular, large, blocky
  • Vertical pupil (don't get close enough to look!)
Never rely on only one characteristic to identify a snake.
