The jararaca is a highly venomous pit viper from South America. It is an important cause of snakebites in the areas where it lives. Its venom also gave scientists a peptide that was used to develop a family of heart and blood pressure drugs.1

Wat eet dit?

Juveniles mainly eat frogs and arthropods, while adults mostly eat mammals, and about 80% of an adult's diet is rodents. It is an ambush predator, relying on good camouflage to catch prey. Juveniles also wiggle their white tail tip to lure prey, which looks like an insect larva.1

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

In southeastern Brazil, this species caused 52% (3,446 cases) of snakebites recorded between 1902 and 1945, with a fatality rate of 0.7%. Its systemic symptoms can be fatal.1

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

As dit byt

Get to a hospital fast. In a recorded case, a patient was treated in hospital with bothropic antivenom and fluid replacement.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.

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

The drugs known as ACE inhibitors, used to treat high blood pressure and some types of heart failure, were developed from a peptide found in this snake's venom. Brazilian scientist Sérgio Henrique Ferreira developed them in 1965.1

An enzyme derived from the venom, called haemocoagulase, is used as an anti-haemorrhagic drug, meaning it helps stop bleeding.1

Males mate with more than one female, and males sometimes fight over females.1
