Uni qanday tanish mumkin

  • 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

Koʻpincha adashtiriladi: 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

Chaqqanda zahar zaharli tishlari yoki tishlari orqali chiqadi.

Uning zahari (chaqsa yoki nish ursa) nima qiladi?

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
