Crotalus scutulatus

Oor die naam: The name comes from the Mojave Desert, although little of the snake's range lies inside that desert.1

Kan doodmaakKan jou doodmaak sonder behandeling. As dit jou byt, kry vinnig hulp.

Glad nie soos ander ratelslange nie: dit het senuweegif en staan sy grond. 'n Byt kan klein lyk terwyl asemhalingsprobleme ure later kom. Gaan altyd hospitaal toe, selfs as die byt lig lyk.

The Mojave rattlesnake is a venomous pit viper that lives in the deserts of the southwestern United States and northern Mexico. Its venom is among the most studied of any rattlesnake, and it varies a lot from one population to another. Knowing how to recognise it helps people in its range stay safe.1

Leef in

Southwestern USA (California, Arizona, Nevada, Utah, New Mexico, Texas) and mainland Mexico, including Sonora and Chihuahua1

Noord-Amerika

Tuis

It lives in broad desert valleys and lower mountain slopes, usually in sparse vegetation such as creosote, mesquite, cacti and Joshua trees. It avoids dense plant cover and very rocky ground. In hot weather and in winter it shelters in burrows dug by rodents, tortoises and kit foxes.1

Lengte

1,2 m (4,1 ft)1

Topspoed

omtrent 3,7 km/h (2,3 mph)

Op land, rowwe skatting

Wat eet dit?

It is an ambush predator, waiting for prey and then striking. It mostly eats small rodents and lizards.1

Hoe om dit te herken

Has a row of large diamond-shaped blotches along the back, without the dark speckling found on the Western Diamond-backed Rattlesnake.1
The diamonds usually lack the white edges seen on most Western Diamond-backed Rattlesnakes.1
The tail has pale and dark rings, and the dark rings are often narrower than the pale ones.1
The rattle is usually yellow and black, or entirely yellow.1
Its back colour ranges from green to brown, grey or yellowish, so colour alone is not a reliable guide.1

Word dikwels verwar met: It closely resembles the Western Diamond-backed Rattlesnake, which lives in the same areas. The Mojave rattlesnake has no dark speckling on its back, usually lacks white edges on the diamonds, has a facial stripe that bends toward the neck rather than meeting the mouth, and usually has a yellow or bicoloured rattle rather than a black one. No single trait reliably separates the two.1

Gifkrag

Byte

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

Wat doen sy gif as dit byt of steek?

Its venom comes in two main types. Venom A contains Mojave toxin, a neurotoxic venom that attacks the nerves and can cause delayed respiratory paralysis, meaning the muscles used for breathing fail, with little or no local tissue damage. Venom B has no Mojave toxin and instead contains tissue-destroying enzymes called metalloproteinases.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

For decades this snake has been described as one of the deadliest rattlesnakes, and some sources call it the most dangerous snake in the United States. The danger depends on the population, because the neurotoxic venom is not found everywhere in its range. Some animals in between produce a mix of both venom types.1

Wat doen dit as dit bang is?

It is shy and tends to avoid confrontation, but it will strike and bite vigorously when disturbed, especially if surprised or if there is no nearby vegetation or burrow to escape into.1

As dit byt

Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

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

die moeite werd om te weet

Feite

Its venom varies so much between populations that one area was found where the venom is much less lethal to laboratory mice than elsewhere in its range.1

Males can grow to a maximum of about 124 cm, making them larger than females.1

Mite-breker

Mite: Every Mojave rattlesnake bite is extraordinarily deadly.

Waarheid: The reputation for deadliness comes mainly from the neurotoxic venom, which is found in most populations but not all. Venom from some populations is non-neurotoxic and mainly destroys tissue.1
