Heterodon is a genus of nonvenomous colubrid snakes commonly referred to as hognose snakes. They are characterized by their upturned snout, which is used for digging in the soil. They are typically found in North America, ranging from Canada to Mexico. They have a lifespan of up to 10 years and their population is currently stable. Heterodon snakes are usually small to medium-sized, with a length of up to 3 feet. They have a wide variety of colors and patterns, including shades of brown, gray, yellow, and black. They have a distinctive pattern of dark spots or blotches on their back.
Name Origin: The name Heterodon is derived from the Greek words "heteros" meaning "different" and "odous" meaning "teeth". This is in reference to the two different types of teeth found in the species, which are the sharp, backward-pointing teeth in the upper jaw and the more rounded teeth in the lower jaw.
