The Texas rattlesnake is a large venomous snake with a characteristic rattle on its tail. It inhabits dry areas of the southwestern United States and hunts small animals.
The Texas rattlesnake differs from other rattlesnakes with large diamonds on its back and a wide head. It helps maintain balance in nature by controlling rodent populations.
