The bullsnake is a non-venomous constrictor found primarily in the central and western United States. It is known for its distinctive coloration, which typically includes a pattern of yellow and brown or tan, helping it blend into its surroundings. Bullsnakes can grow to be quite large, often reaching lengths of 3 to 8 feet. These snakes are often mistaken for the more dangerous rattlesnake due to their similar appearance. Bullsnakes are beneficial to the ecosystem as they help control populations of small mammals and pests. They are also known for their defensive behavior, which includes hissing and mimicking the rattlesnake's rattle when threatened.
