Category: Reptiles · Updated: August 4, 2026

1 Overview

The hognose snake (here the western hognose, Heterodon nasicus) is famous for its upturned snout and theatrical defence: it hisses, flattens its neck, plays dead, then rarely bites. It is harmless and rear-fanged but not dangerous.

SOURCE NOTE: the source gave only ‘hognose snake’; the representative species is Heterodon nasicus.

2 Appearance

Stout with a distinctive upturned rostral scale, 40-80 cm, in a range of browns with blotches. The ‘playing dead’ routine is unmistakable.

3 Care & Temperament

A secure terrestrial terrarium with a sandy substrate for burrowing, a temperature gradient, and hides. Generally easy but can be picky eaters.

Mouth rot follows poor hygiene.

4 Habitat & Environment

Sandy grassland and scrub. Mimic with a diggable substrate, cover, a basking spot, and moderate humidity.

5 Diet & Feeding

Naturally eats toads and amphibians; in captivity accept rodents, sometimes after scenting. Some refuse food – patience and variety help.
