The western hognose snake is a small, stout-bodied snake with an upturned nose that looks a bit like a pig's snout. It lives across much of North America, from southern Canada to northern Mexico, in sandy and gravelly places such as prairies and grasslands. It is often mistaken for a rattlesnake, but its bite is not regarded as dangerous to people.1

Apa makanannya?

It mainly eats amphibians, such as large and medium tree frogs, small or medium toads and small lizards, and occasionally a rodent. It is not a true constrictor, so it bites and chews, driving its rear fangs into prey.1

Fakta

Captive breeders have produced more than 50 'designer' colour morphs of this snake.1

In captivity, many hognose snakes refuse food for about two to three and a half months, from January to mid March, because they instinctively brumate, or sleep, underground in winter.1

Males are considerably smaller than females.1

Hatchlings reach sexual maturity after about two years, based mostly on size rather than age.1

Mitos: Because it looks like a rattlesnake, it must be dangerous or deadly.

Faktanya: The western hognose snake is not dangerous to people. Its rare bites have not caused recorded deaths or whole-body effects, and it usually plays dead instead of biting.1
