Hognose Snakes – Why Do They Have a Nose?

Hognose snakes (Heterodon platyrrhines) feature an upturned snout used for digging. While not venomous, their saliva contains mild toxins that may subdue prey. Choose the hognose snake for sale.

As snakes are preyed upon by predators such as raccoons, Virginia opossums, foxes, predatory birds, and other snakes when attacked, they typically respond by flattening out their neck and head like a cobra and hissing; if that fails, they will play dead.

Why Do They Have a Nose?

Heterodon platyrrhines snakes have an upturned snout, giving them their common name: Eastern Hognose Snake. Their upturned nose allows them to dig for toads, their favorite food source. Furthermore, these reptiles possess large teeth in the back of their mouths that help pop inflated toads for easier swallowing.

Hognose snakes don’t see well and have poor hearing, so they use their nostrils to detect vibrations in the ground – helping them find toad caves where they hibernate underground.

Hognose snakes make an impressive showing when sensing danger by flattening their heads and hissing loudly or playing dead, as is sometimes genetically pre-programmed into them by their parents.

Hognose snakes don’t usually bite people but may still cause minor symptoms when mishandled. Always use gloves when handling these reptiles to protect your health and that of the snake you’re holding and avoid issues like scale rot, mouth rot, and respiratory conditions that arise from improper handling. Also, ensure you provide enough water in an enclosed and warm location so it can soak.

Why Do They Play Dead?

Hognose snakes have an instinctual response when threatened: when rolling onto their back and sticking out its tongue in an elaborate display of death. This behavior, known as thanatosis, has been part of their natural behavior from birth and is crucial for survival.

Hognose snakes can use another tactic to appear dead: emitting foul smells from their cloaca to create the impression that they’ve been dead for some time – this deters predators and convinces prey animals that the snake has already died, making eating it harder. Even baby hognose snakes can use this strategy.

The hognose snake’s upturned snout is one of the signature characteristics distinguishing it from other colubrids (reptiles with front-fanged teeth) and assists it in digging in sandy soil. These serpents primarily inhabit woodlands, farmland, and coastal areas in the Eastern United States but may also be found in wetlands; their prey includes frogs, salamanders, birds, mammals, spiders, invertebrates, and toads.

Why Do They Burrow?

Hognose snakes belong to the Heterodon genus in the Colubrid family and exhibit several distinctive features that set them apart from other snake species. Their characteristics are remarkable but combined, make the species even more intriguing.

Hognose snakes play dead only when their lives are genuinely threatened; this behavior is instinctual to their survival strategy and should not be treated as an entertainment stunt or a learned trick. When approached by predators, hognose snakes roll over and emit unpleasant odors from their cloacas that convince most predators that the animal is already deceased, discouraging attempts at biting.

The eastern hognose snake, found from Minnesota to Florida, can flatten its neck like a cobra when threatened. Unfortunately, this defensive response is often mistaken for brumation, wherein snakes become lethargic due to an inadequate heat source. Furthermore, its upturned snout allows digging in soil in search of toads as its primary prey item, and it produces mildly toxic saliva that helps subdue its prey before seeing or impaling with its back teeth.

Why Do They Eat Toads?

Hognose snakes use their upturned snout to dig in the ground. They are particularly adept at searching through sandy soil to search for Heterodon platirhinos frogs, which make up a significant portion of their diet.

The eastern hognose snake boasts an enormous mouth accommodating an inflating toad (Bufo sp). Once in their grasp, its rear fangs produce a mild toxin that deflates it quickly.

Hognose snakes use their coiling necks to produce sound and make noise to scare away predators, and should the threat become severe enough, they will play dead by rolling onto their bellies, writhing about, and sticking their tongues out as if dead. This behavior is an instinctual response designed to protect themselves in the wild; new pet keepers should understand this natural behavior. Otherwise, getting their newborn snake to feed properly may prove challenging.
