Anatomy Of Western Hognose Snake

The Western hognose snake is a unique and fascinating creature with physical features that make it easily identifiable in its natural habitat.

  • Appearance

The most distinctive feature of the Western hognose snake is its upturned snout, which gives it a hog-like appearance. This feature helps burrow under the soil quickly and catch prey such as toads, frogs, and rodents. 

Their average size is approximately 14-24 inches long, and their scales have a keeled texture that allows them to crawl through various environments. They have a relatively thick body with multiple patterns and colorations, typically grey to brown. They have a unique habit of playing dead, which includes flipping on their backs, opening their mouths, and emitting a foul-smelling odor.

  • Venom Glands

Like all other snakes; the Western hognose snake has venom glands just behind their eyes. Although venomous, their bite poses no dire threat to humans, and fatalities from their bites are rare. In most cases, a bite will cause swelling, and localization will subside within a few hours. Unless you have an allergy, the Western hognose snake’s venom is not fatal, and medical attention is not typically necessary. 

Western Hognose Snake Feeding Habits

Western hognose snakes are primarily diurnal and feed on small prey, including mice, voles, lizards, frogs, and insects. They use their upturned nose to dig through the soil for prey. They swiftly strike and immobilize prey using venom. Unlike snakes, they don’t coil around their victim but swallow it whole with their wide-open jaws. It’s a unique hunting technique that showcases their hunting prowess and distinguishes them from other snakes.

Defensive Mechanisms

Western hognose snakes have developed various defensive mechanisms despite their non-threatening disposition towards humans. When Western hognose snakes sense danger, they have a distinctive defense mechanism. They flatten their necks, emit a hiss, and release an unpleasant odor from their cloaca. 

It’s their way of warding off potential threats and ensuring their safety. They may strike with a closed mouth or the blunt end of their head or even play dead. In extreme cases, they may resort to biting as a last resort.

Effects Of Western Hognose Snake Bite

The Western hognose snake is venomous, but its bite is not dangerous to humans. The bite of this snake is relatively mild, and fatalities from their bites are rare. Most bites are painless, and the amount of venom injected is insufficient to cause severe symptoms. However, in rare cases, the bite may cause an allergic reaction.

  • Symptoms

The symptoms of a Western hognose snake bite may vary from mild to severe and can occur within minutes to hours. Common symptoms include pain, swelling, redness at the bite site, numbness or tingling in the affected area, nausea, vomiting, and headache. More severe symptoms that may occur in rare cases include respiratory distress, muscle weakness, and anaphylaxis.

  • Treatment Of Bite

If a Western hognose snake has bitten you, it is essential to seek medical attention immediately. The first step is to clean the bite wound with soap and water and cover it with a clean, dry dressing. It is crucial not to try to suck out the venom or cut the bite site. These actions can cause more harm than good.

Treating a Western hognose snake bite may include pain control, wound care, and antivenom therapy. 

Antivenom therapy is the most effective treatment for severe symptoms such as respiratory distress and anaphylaxis. It is essential to note that antivenom therapy should only be administered by a medical professional and in a hospital setting.
