The Mexican west coast rattlesnake is a large venomous pit viper. It lives on the coastal plain of western Mexico. It is one of the largest rattlesnakes in the world, so its size and its strong venom make it one to respect.1

Leef in

Western Mexico, from southern Sonora to Michoacán, mostly on the coastal plain.1

Noord-Amerika

Tuis

Its habitat is mostly tropical thorn forest, extending into tropical deciduous forest. Around Colima, where it is particularly plentiful, the land is mostly treeless with short grass, scattered mesquite, acacias, thorny bushes and many large cacti. In the lowlands, most specimens are found crossing roads at night.1

Lengte

1 m tot 2 m (3,3 ft tot 6,7 ft)1

Gewig

700 g (1,5 lb)1

Topspoed

omtrent 4,2 km/h (2,6 mph)

Op land, rowwe skatting

Wat eet dit?

The stomachs of seven specimens contained mammal hair, probably from rodents.1

Hoe om dit te herken

Brown or grey body with 26 to 41 dark, diamond-shaped blotches that have light edges.1
Within its range, it is the only rattlesnake with diamond-shaped markings on its back.1
Head is a uniform greyish-brown, with lighter lip scales and a dark bar behind each eye.1
Young snakes are mostly red, and adults become olive green.1
Body is moderately stout and rather rectangular in cross section.1

Word dikwels verwar met: It often lives in the same areas as C. molossus, and the two hybridise freely. The two species are easy to tell apart, but hybrid snakes are hard to identify.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 is highly toxic and is produced in large amounts. The venom contains proteases, which are enzymes that break down proteins. In some populations, it may also contain a component related to Mojave toxin.1

Hoe gevaarlik is dit vir mense?

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

Large specimens should be regarded as very dangerous. An average venom yield of 297 mg of dried venom has been recorded.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.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
