Did you know?
- Bullsnkaes are part of the family Colubridae, which they share with other nonvenomous snakes.
- They live throughout the Midwest and Southwest U.S.
- They are typically active from April through early November.
- They eat small mammals, including mice and rabbits, and birds.
- A female will lay between three to 22 eggs per clutch.
Bullsnakes can be over seven feet long, making them the longest snakes in Missouri and formidable predators. Their mixed-brown coloration is perfect for camouflaging in forests and vegetation, and the shape of their pointy head is ideal for burrowing and digging in dirt.
