What are the three recognized species within the genus Heterodon?
Answer
Western Hognose (*H. nasicus*), Eastern Hognose (*H. platirhinos*), and Southern Hognose (*H. simus*).
The genus *Heterodon* is comprised of three distinct, recognized species. These are the Western Hognose snake, scientifically designated as *H. nasicus*; the Eastern Hognose snake, *H. platirhinos*; and the Southern Hognose snake, *H. simus*. Although they share key characteristics, such as the defining rostral scale, their evolutionary paths have diverged based on specific habitat requirements and the availability of local prey resources across their respective ranges in North America.
