Description

The Dusky Pygmy Rattlesnake, often called the "Ground Rattler", is a heavy-bodied snake. The body of the snake is brown or grey. A reddish-orange or rust colored stripe often runs along the spine. The snake is marked by dark brown or black blotches along its spine that appear to cover the reddish-orange stripe. There is also three rows of dark brown or black blotches on its sides. There is a dark cheek-stripe on both sides of the head that starts at the eye and runs diagonally down and backwards to the jaw above the mouthline. The bottom of the cheek-stripe is often edged in white. The top of the head is often marked by two stripes that continue on to the neck. The end of the tail has a small rattle on it that is seldom lounder than a buzzing insect, and is often not heard or even seen.
