The western massasauga is a small, venomous rattlesnake. It lives on the grassy plains and deserts of the southwestern United States and northern Mexico. Its rattle is higher pitched than those of bigger rattlesnakes, so it can be easy to miss as a warning.1

Hoe om dit te herken

Dark brown blotches stand out strongly against a tan-grey or light grey background.1
The belly is light, with a few dark markings.1
Adults range from 35 to 91 cm in total length, tail included.1
It has a rattle, but it is higher pitched than the rattles of larger rattlesnakes.1

Word dikwels verwar met: Its colour pattern is similar to that of the eastern massasauga, but paler. The dark brown blotches contrast more strongly with its light ground colour.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 a powerful hemotoxin, which damages blood and tissue. It can cause swelling, necrosis (death of body tissue) and severe pain. Its yield is low, so each bite delivers less venom than a larger rattlesnake's bite would.1

Hoe gevaarlik is dit vir mense?

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

Its bite is less severe than that of larger rattlesnakes because it delivers less venom. Even so, the bite can be fatal if it is not treated.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

Its rattle is not a reliable warning, because its high pitch is easy to miss.1

As dit byt

Treatment should be sought immediately for any venomous snake bite. The antivenin CroFab is not specific to this snake, but it can be used to treat severe envenomation from massasaugas.1
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.

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 is as potent as that of larger rattlesnakes, but its low yield greatly reduces the harm it can do.1

It is nicknamed the buzztail because of its high-pitched rattle.1

It is mainly active at night and is considered mild-mannered and sluggish, especially in summer, when it is sometimes found basking.1

It was once considered a subspecies of the eastern massasauga.1

Mite-breker

Mite: A rattle always gives a clear warning before a rattlesnake bites.

Waarheid: The western massasauga's rattle is higher pitched than those of larger rattlesnakes, so it should not be relied on as a warning.1
