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

Kaj je?

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

Kako jo prepoznaš

Relatively small and stout-bodied, with adults rarely exceeding 40–50 cm in total length, tail included.1
A modified, upturned nose scale gives it a distinctive hog-like snout.1
Colour and pattern vary a great deal between subspecies and individuals.1
When threatened, it flattens its neck, hisses and may puff up its throat with air.1

Pogosto zamenjujejo z: To an untrained eye, most individuals look much like rattlesnakes, which is thought to be a form of mimicry that makes predators wary. Its upturned snout and small, stout body are features to note.1

Kaj naredi njen strup, ko ugrizne ali piči?

The snake releases modified saliva from its Duvernoy's glands, which runs down a groove in its rear fang and helps break down the toxins of toads it eats. No deaths or whole-body (systemic) effects in people have been recorded from its bite. Bites may occasionally be medically significant.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BlagaKot čebelji pik ali manj. Za ljudi praktično neškodljiva.

The species is not dangerous to people and is not regarded as venomous. Its bites are extremely rare, and no deaths or systemic effects have been recorded. Bites may uncommonly be medically significant.1

Kaj naredi, ko se prestraši?

It flattens its neck, hisses and may make mock strikes with its mouth closed. If harassed further, it usually plays dead rather than biting.1

Če ugrizne

Ugriz umij, poškodovanca pomiri in poišči zdravniško pomoč. Nekatere vrste (na primer bumslang) so lahko smrtno nevarne še čez nekaj ur.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

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

Resnica: 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
