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

Leef in

Southern Canada, through the United States, to northern Mexico. Endemic to North America.1

Tuis

It favours areas with sandy or gravelly soils, including prairies, river floodplains, scrub, grasslands, semi-deserts and some semi-agricultural land. It has been found at elevations of up to 2,500 m (8,200 feet).1

Lengte

13 cm tot 50 cm (5,1 in tot 1,6 ft)1

Topspoed

Wat eet dit?

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

Hoe om dit te herken

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

Word dikwels verwar met: 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

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

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

Wat doen dit as dit bang is?

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

As dit byt

Was die byt, hou die persoon kalm en kry mediese hulp. Sommige spesies (soos die boomslang) kan ure later dodelik wees.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

Mite-breker

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

Waarheid: 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
