The saw-scaled viper is a small, venomous snake of the Middle East, Central Asia and the Indian subcontinent. It is the smallest of the 'big four' Indian snakes that cause the most snakebite cases and deaths. It is easy to miss, which is one reason it causes so many bites.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 causes swelling and pain within minutes of a bite, and the swelling can spread up the whole limb within 12 to 24 hours, with blisters forming on the skin. The more dangerous effects are whole-body: bleeding and clotting problems, bleeding from the stomach, lungs, nose or urine, and possible shock. Most patients produce little or no urine within a few hours to six days after the bite.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: DodelikEen van die gevaarlikste diere in die wêreld.

About 20% of its bites used to be fatal, but deaths are now quite rare because antivenom is available. It is one of the species responsible for the most snakebite cases because it is inconspicuous and extremely aggressive.1

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

Wat doen dit as dit bang is?

When threatened it forms a double coil in a figure of eight, with its head in the centre, so it can lash out like a released spring.1

As dit byt

Antivenin therapy and intravenous hydration within hours of the bite are vital for survival.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

Feite

On average it produces about 18 mg of dry venom, with a recorded maximum of 72 mg. The lethal dose for an adult is estimated at only 5 mg.1

When it rains, up to 80% of the adult population may climb into bushes and trees. Once, about 20 individuals were seen massed on one cactus or small shrub.1

It moves mainly by sidewinding, a method it is very skilled at and surprisingly quick with. Only two points of its body touch the hot ground, which may help it avoid overheating.1

Its venom is used to make several drugs, including echistatin, an anticoagulant that can be made by chemical synthesis, and ecarin, used in a clotting test.1

In the northern parts of its range, it hibernates in winter.1
