“Hognose snake” is a common name for several North American snakes in the genus Heterodon, not one single species. The eastern hognose (H. platirhinos), plains or western hognose (H. nasicus) and southern hognose (H. simus) differ in range, habitat, prey, size and conservation concerns. All are recognized for an upturned snout used in digging, and some respond to danger with dramatic bluffing or death-feigning.
Which snakes are called hognose snakes?
In North American natural-history sources, “hognose” generally refers to Heterodon species. This profile focuses on three commonly discussed forms:
| Species | Where and how it lives | Food emphasis | Documented adult size | Conservation context |
|---|---|---|---|---|
| Eastern hognose (Heterodon platirhinos) | Eastern North America; uses its shovel-like snout to dig, including when searching for buried toads. See the North Carolina Wildlife Resources Commission profile. | Strong association with toads and other amphibians. | Not stated in the cited sources. | Local rules and conditions vary by state; consult the relevant wildlife agency. |
| Plains (western) hognose (Heterodon nasicus) | Open, often sandy habitats in the Great Plains and adjacent regions; burrows in loose soil. | Frogs and toads, plus birds, small mammals and eggs listed by the National Park Service. | 15–26 inches for the population described by NPS. | Status depends on jurisdiction; the cited NPS profile is a natural-history account, not a range-wide legal designation. |
| Southern hognose (Heterodon simus) | Sandy fields, sandhill, open grassland and suitable woods in parts of the southeastern Coastal Plain. | Primarily toads and other amphibians; documented prey also include spadefoots, lizards and invertebrates. | 18–22 inches according to the Florida Fish and Wildlife Conservation Commission profile. | North Carolina lists it as state threatened. Habitat loss, fragmentation, roads and collection are identified threats. |
“Western hognose” is a common pet-trade name for the plains hognose. Names and subspecies usage can differ among authorities, so a scientific name is the clearest way to identify the animal being discussed.
How to identify a hognose snake
The upturned snout
The enlarged, upturned rostral (nose) scale is the defining feature. It acts like a small shovel, helping the snake loosen sandy soil, uncover prey and make or use shallow burrows. The eastern hognose is specifically documented digging for toads, while plains hognose snakes are associated with sandy-soil digging.

Body shape and pattern
Plains hognose snakes in the NPS account are robust, tan to light brown and marked with darker dorsal blotches. Florida’s southern hognose profile describes a heavy-bodied snake, usually gray, tan or reddish, with dark blotches. Eastern hognose coloration is especially variable, so color alone is not a reliable species test.
Where do hognose snakes live?
Habitat depends on the species. Eastern hognose snakes occupy parts of eastern North America and select places where loose soil and amphibian prey are available. Plains hognose snakes are associated with open, sandy environments across the Great Plains and nearby areas. Southern hognose snakes are tied to sandy uplands, sandhill and open Coastal Plain habitats in the Southeast. Development can remove or divide the specialized open, sandy habitat that southern hognose populations need; a snake’s presence in one county therefore does not establish that it is secure throughout its range.
What do hognose snakes eat?
Eastern and southern hognose snakes
Toads and other amphibians are central to the documented diets of eastern and southern hognose snakes. The southern hognose conservation plan records spadefoots, other toads, lizards and invertebrates in addition to its principal amphibian prey. A hognose’s digging snout is useful for locating prey hidden under loose soil.
Plains hognose snakes
The National Park Service lists frogs and toads, birds, small mammals and eggs for plains hognose snakes. This broader list should not be used to assume that every Heterodon species feeds the same way or in the same proportions.

Hognose snakes are not considered dangerous to people in the cited agency profiles, but “not dangerous” is more accurate than claiming that a bite can never cause a reaction. All Heterodon have a pair of enlarged, ungrooved rear teeth and oral-gland secretions. The U.S. Fish and Wildlife Service southern hognose assessment reports a few human reactions, usually after a sustained bite, and states: “Specifically, the toxicity of the southern hognose snake has not been tested.” That finding concerns the southern species and should not be generalized into a measured toxicity value for every hognose.
Do not handle a wild snake to test its teeth or provoke a bite. If a bite occurs, wash the wound, seek medical advice for persistent or worsening symptoms, and tell clinicians which species or location is known.
Do hognose snakes play dead?
They can. A threatened hognose may flatten its head and neck, hiss, bluff-strike and, in some individuals, roll over and feign death. The sequence and intensity vary; not every snake performs every display. Death-feigning is a defense intended to make a predator lose interest, not evidence that the snake is harmless to touch.

Southern hognose snakes can be locally common in some Florida uplands yet scarce or absent from developed counties. Florida wildlife officials identify habitat loss, degradation and fragmentation, highway mortality and collection as threats. North Carolina lists the species as state threatened. The 2025 federal materials concerning the southern hognose were a proposed rule and accompanying status assessment, not a final range-wide legal-status determination; check the current U.S. Fish and Wildlife Service and state listings before relying on a regulatory claim.

Handling, ownership and captive care
Hognose snakes are often kept by experienced reptile keepers, but a species-appropriate enclosure is not interchangeable across eastern, plains and southern forms. Burrowing substrate, secure hides, ventilation, heating control and a prey plan must be selected for the identified species and local veterinary support. The ReptiFiles Hognose Snake Care Guide covers North American Heterodon and is a starting point, not a substitute for an exotic-animal veterinarian.
Possession, collection and transport laws vary by state and may differ for wild-caught and captive-bred snakes. No single legality statement covers all three species; contact your state wildlife authority before acquiring or collecting one.
Quick field-identification checklist
- Look for the characteristic upturned snout, but confirm the species with range and pattern.
- Record habitat: sandy soil, sandhill, open grassland and woodland edges can narrow the possibilities.
- Expect bluffing—flattening, hissing, mock strikes or death-feigning—when the snake feels threatened.
- Keep a safe distance and never pick up a snake solely to identify it.
- Use a scientific name when reporting a sighting, purchase or conservation concern.
Frequently Asked Questions
Are hognose snakes good pets?
They can be suitable for knowledgeable keepers, but care must be matched to the exact Heterodon species and local veterinary and legal requirements. A general setup should not be assumed to fit every hognose.

What should I do if a hognose snake is in my yard?
Give it space and let it leave on its own. Hognose defensive displays are normal; do not corner, handle or provoke the snake.
