The prairie rattlesnake is a venomous pit viper that lives across the Great Plains and the foothills of the Rocky Mountains. It is found in the western United States, southwestern Canada and northern Mexico. It shakes its tail to give a rattling warning when it feels threatened.1

Hoe om dit te herken

Usually lightly coloured in shades of brown, with patches of dark brown along the back1
A colour band may be seen at the back of the eye1
A triangle-shaped head with pit sensory organs on either side1
Usually four internasal scales on the snout, with three or more in total1
Commonly grows to more than 100 cm long1

Word dikwels verwar met: Other rattlesnakes can look similar. A key difference is that two internasal scales touch the rostral scale, at the tip of the snout, in the prairie rattlesnake.1

Gifkrag

Byte

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

Wat doen sy gif as dit byt of steek?

The venom is a complex mixture of proteins, including enzymes such as proteases and peptidases. It is hemotoxic, meaning it damages blood and destroys tissue. It also has neurotoxic properties, meaning it attacks the nerves.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

The species has powerful venom and uses about 20 to 55% of its venom in one bite. It will defend itself if it is threatened or injured.1

Wat doen dit as dit bang is?

It rapidly vibrates its tail to make a rasping rattle that warns intruders, and it will defend itself if threatened or injured.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

Feite

Females often gather in communal dens to give birth and care for their young. Some females even look after unrelated young while the mothers take a break.1

Newborn snakelets measure 22 to 28 cm and are venomous from the moment they are born.1

Prairie rattlesnakes prefer a straight migration path, even in areas dominated by humans, because it gives them a better chance of survival.1

In Montana, the species reaches its largest size, with specimens sometimes exceeding 120 cm.1

In Canada, the species is listed as a species of special concern because its numbers have steadily declined since the 1930s.1
