Heterodon platirhinos, commonly known as the eastern hog-nosed snake,spreading adder, or deaf adder, is a harmless colubrid species endemic to North America. No subspecies are currently recognized.
Heterodon platirhinos is found from eastern-central Minnesota, and Wisconsin to southern Ontario, Canada and extreme southern New Hampshire, south to southern Florida and west to eastern Texas and western Kansas.
The average adult measures 71 cm (28 in) in total length (body + tail), with females being larger than males. The maximum recorded total length is 116 cm (46 in).
The most distinguishing feature is the upturned snout, used for digging in sandy soils.
The color pattern is extremely variable. It can be red, green, orange, brown, gray to black, or any combination thereof depending on locality. They can be blotched, checkered, or patternless. The belly tends to be a solid gray, yellow, or cream-colored. In this species the underside of the tail is lighter than the belly.
Although H. platyrhinos is rear-fanged, it is often considered nonvenomous because it is not harmful to humans. Heterodon means "different tooth", which refers to the enlarged teeth at the rear of the upper jaw. These teeth inject a mild amphibian-specific venom into prey, and also are used to "pop" inflated toads like a balloon to enable swallowing. Bitten humans who are allergic to the saliva have been known to experience local swelling, but no human deaths have been documented.
