Overview

The eastern hognose snake is renowned for one of the most elaborate defensive performances in the snake world. When threatened, it first flattens its neck into a cobra-like hood and hisses loudly; if that fails, it dramatically writhes, flips onto its back, and feigns death with its mouth agape.

Its distinctive upturned, shovel-like snout is an adaptation for digging, particularly for unearthing its preferred prey of toads.

How to identify it

  • Stout body with a distinctly upturned, pig-like snout
  • Highly variable coloration: gray, brown, olive, yellow, orange, or nearly black, often with blotching
  • Keeled scales giving a rough texture
  • Flattens neck into a hood when threatened, resembling a small cobra
  • Distinguished from other colubrids by the unique upturned rostral scale

Habitat & range

Prefers sandy or loose soils in open woodlands, fields, and coastal plains across the eastern United States, useful for burrowing in search of toads. Also found in scrublands and floodplain habitats.

Behavior, diet & reproduction

Diurnal and most active in warm months. Feeds heavily on toads, using enlarged rear teeth and mildly toxic saliva to help subdue prey resistant to predation by other snakes. Egg-laying, with clutches buried in sandy soil.
