Crotalus atrox

Western Diamond-backed Rattlesnake

Western Diamond-backed Rattlesnake from Val Verde County, Texas.

The black and white banding on the tail gives them the nickname "Coontail Rattler".

This gravid (pregnant) female rattler was seen basking on a quiet dirt road in Irion County, Texas.

The width of the last half of the snake indicates the she is probably gravid (pregnant).  She was gently lifted of the road to find a safer basking spot.

This Western Diamond-backed Rattlesnake is coiled in a typical hunting posture beside a road in Starr County, Texas. 

Rattlesnakes will sit in these positions for days at a time waiting for an unlucky mouse or rat to come within range of their strike.
