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

Paano ito makikilala

  • 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

Madalas mapagkamalang: 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

Lakas ng kamandag

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

Panganib sa tao: MalalaKailangang magpatingin sa doktor kapag nakagat. Napakabihira ng namamatay.

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

Ano ang ginagawa nito kapag natatakot?

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

Kung kumagat ito

  • Panatilihing hindi gumagalaw at kalmado ang tao, panatilihin ang nakagat na braso o binti sa antas ng puso, tanggalin ang mga singsing at masisikip na bagay, at pumunta agad sa ospital.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

  • Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
  • Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
  • Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat
