The Saharan horned viper is a venomous snake that lives in the deserts of North Africa and parts of the Arabian Peninsula. It has a pair of small, horn-like scales above its eyes. Its venom can cause serious harm, so it is important to know what it looks like.1

Nola ezagutu

  • A pair of horn-like scales sits above each eye, although some individuals have no horns.1
  • Its colour is yellowish, pale grey, pinkish, reddish or pale brown, and almost always matches the sand or soil where it lives.1
  • A row of dark, semi-rectangular blotches runs along its back, and the belly is white.1
  • Its tail is usually thin and may have a black tip.1
  • It moves by sidewinding, pressing its body into the sand and leaving whole-body impressions.1

Askotan honekin nahasten da: Its close relative Cerastes gasperettii was once considered a subspecies of this snake. The Saharan horned viper has a larger head relative to its body and horns are more common in it. When threatened, it rubs its coils together to make a rasping noise, which is similar to the sound made by snakes of the genus Echis, so sound alone does not identify it.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

Its venom is reported to act much like the venom of Echis snakes. A bite usually causes swelling, bleeding (haemorrhage), tissue death (necrosis), nausea, vomiting and blood in the urine. A high level of phospholipase A2, an enzyme that damages cells, may cause heart and muscle damage.1

Arriskua pertsonentzat: LarriaKoska batek medikua behar du. Heriotzak oso arraroak dira.

The estimated lethal dose of venom for a human is 40–50 mg of dried venom. Its venom is strong enough to cause serious harm in people.1

Zer egiten du beldurtzen denean?

If threatened, it forms a C-shaped posture and rapidly rubs its coils together, producing a rasping noise. It is otherwise fairly placid.1

Kosk egiten badu

  • Eutsi pertsona geldi eta lasai, eduki koska jasotako gorputz-adarra bihotzaren mailan, kendu eraztunak eta gauza estuak, eta joan ospitalera azkar.

Egon seguru

  • Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
  • Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
  • Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago
