The black-necked spitting cobra is a venomous snake found mostly in sub-Saharan Africa. It can squirt venom from its fangs at a threat, and that venom can cause permanent blindness if it gets into the eyes. Its colours vary a lot from place to place.1

Leef in

Mostly sub-Saharan Africa, in western, eastern, central and parts of southern Africa. Absent from the Congo Basin rainforests.1

Spuit of spoeg

Wat doen sy gif as dit byt of steek?

Its venom is mostly cytotoxic, meaning it destroys cells, and it also has typical elapid neurotoxic (nerve-attacking) effects and cardiotoxic (heart-damaging) components. A bite causes severe bleeding from the wound, tissue death around the bite, and difficulty breathing. Venom in the eyes causes extreme burning pain, loss of coordination, partial loss of vision, and permanent blindness.1

Its venom is medically significant. The death rate for untreated bites is about 5 to 10%, and under 1% in areas where it is common. When death occurs, it is usually from paralysis of the diaphragm, the muscle used for breathing.1

Wat doen dit as dit bang is?

It spits venom from its fangs at a threat, reaching up to 7 metres with good accuracy. It also bites readily, even with only slight provocation.1

As dit byt of spoeg

If venom gets into the eyes, it should be washed off, because permanent blindness can follow if it is not. Anyone bitten should get medical treatment, as untreated bites carry a much higher risk of death.1
Hou die persoon stil en kalm, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit: teengif is die behandeling.
As gif in die oë gespoeg is, spoel hulle dadelik met baie skoon water 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 of gif in jou oë spoeg: 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

It can spit venom accurately more than 7 metres away.1

In 1944, a British eye surgeon, Major Harold Ridley, described eye damage from a spit from this cobra in Ghana. He treated the man and followed his case until the eye fully recovered.1

A single bite can deliver 200 to 350 mg of venom (dry weight), according to a 1974 study by Minton.1

It is an excellent tree climber and can live in trees at times.1

Wild-caught individuals tend to be nervous and spit readily, while captive-bred animals are much calmer.1

It can be active at night or during the day, depending on the season, location and temperature.1

Mite-breker

Mite: Spitting cobras only spit venom and do not bite.

Waarheid: The black-necked spitting cobra also bites, and it will do so with only slight provocation.1
