Eastern Hognose Snake

Heterodon platirhinos

Also known as Eastern Hog-nosed Snake, Puff Adder, Spreading Adder, Blow Viper

Famous for dramatic theatrical defenses, the eastern hognose snake flattens its head and neck like a cobra, loudly hissed, and strikes with a closed mouth when cornered. If this bluff fails, it rolls onto its back, hangs its tongue out, and plays dead until danger passes. Its spade-like upturned snout is a specialized adaptation for digging through loose, sandy soil to unearth burrowed toads.

What to notice
Recognizable by its stocky body, upturned snout, variable color pattern, and habit of flattening its neck into a cobra-like hood.
Support conservation
Keep a respectful distance, avoid harassing the animal, and let it clear its defensive display without cornering it.
Responsible observation
  • Observe Display: Watch from a few paces away if it flattens its neck, allowing it to relax and move on naturally.
  • Do Not Touch: Avoid picking up or handling the snake, which causes intense stress and can provoke death-feigning or regurgitation.
  • Protect Habitat: Keep distance in sandy field edges where toads and snakes actively forage.
