The Western Timber Rattlesnake, scientifically known as Crotalus-horridus, is a venomous snake found primarily in the central and eastern regions of the United States. It typically inhabits forests, rocky hillsides, and grasslands. This species is recognizable by its distinctive rattling tail, which it uses as a warning signal to potential threats. These snakes can grow to lengths of 3 to 5 feet and have a color pattern that varies from yellow to gray, often featuring dark bands. The Western Timber Rattlesnake plays a crucial role in its ecosystem by controlling rodent populations and serves as an important indicator of environmental health.
