Overview
The eastern hognose snake is renowned for one of the most elaborate threat displays 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.
