Venomous snakes - series
Toggle: English / Spanish
This is a rattlesnake.
The top row displays the defining features of a rattlesnake. From left to right, a rattle on the tail, a triangular head, and hinged fangs.
One way to determine if a snake is venomous is to look at its underbelly. If there is a single row of scales leading to the anal plate, the snake is venomous.
