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

It is often met in villages and small towns, where it may come into direct contact with people. It hides in tree trunks, termite mounds and rodent holes.1

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

Tge fa el, cura ch'el ha tema?

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

Sch'el morda u spida

  • 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
  • Tegna la persuna immobila e quieta, prenda giu anels e chaussas strenschidas e va spert en in ospital: l'antiserum è il tractament.
  • Sch'il tissi è vegnì spidà en ils egls, lava ora quels immediat cun bler'aua netta.

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