Eastern Hog-Nosed Snake by alumroot

Common names: eastern hog-nosed snake, spreading adder, hog-nosed snake.

Heterodon platirhinos is a harmless colubrid species found in North America. No subspecies are currently recognized.

Adults average 71 cm (28 inches) in length, with females being larger than males. The most distinguishing feature is the upturned snout, used for digging in sandy soils.

The color pattern is extremely variable. It color can be red, green, orange, brown, grey to black, or any combination therein depending on locality. They can be blotched, checkered, or patternless. The belly tends to be a solid grey, yellow or cream colored.

These snakes are considered rear-fanged, but any venom they excrete is not considered dangerous to humans and they are not inclined to bite.
