The spider-tailed horned viper is a venomous snake with a tail tip that looks like a spider. It lives only in the mountains of western Iran and the nearby eastern part of Iraq. It wiggles its tail to lure birds close enough to catch.1

It lives at higher elevations, mostly on rocky ground made of gypsum, and prefers deep cracks and holes in the rock. These spots trap humidity and moisture during hot summers. During the day it is most often found in the shade of a shrub.1

Nola ezagutu

  • The scales above each eye rise up into small horns.1
  • About 16 to 17 scales sit between the horns.1
  • The bulb-shaped tail tip is bordered by long, drooping scales that look like spider legs.1
  • The scales on the body are rougher than those of other species in its genus.1
  • It has 15 pairs of subcaudal scales (the scales on the underside of the tail).1

Askotan honekin nahasten da: It looks very similar to other Pseudocerastes vipers in the region, especially around the head. The unusual, spider-like tail tip is the feature that sets it apart.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

Its venom mainly acts as a cytotoxin, which destroys cells across a wide variety of cell types, and it has minor neurotoxic effects, which attack the nerves. It is a procoagulant, meaning it makes blood clot, and reports describe clotting in about 13 seconds. The venom affects birds most strongly, and also affects mammals and amphibians. A 2021 study by Brouw found it has a coagulant effect on humans and affects Factor X, a protein needed for blood clotting.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.

Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak

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

Datuak

1

Its tail is moved in a figure-of-eight pattern, and it moves faster when birds are nearby. Field studies have confirmed that this is a lure and not random movement.1

2

Footage of it luring migrating birds appears in the Asia episode of the BBC series Seven Worlds, One Planet, narrated by David Attenborough.1

3

A digested lark was found in the stomach of one of the specimens used to describe the species, supporting the idea that the tail lures birds.1

4

Its tail tip is a form of aggressive mimicry, where a predator looks like something else to attract its prey.1

5

Several other snakes, such as the sidewinder and the green tree python, also use the tip of their tail as a lure, but none has the elongated scales that look like arthropod legs.1

6

A specimen collected in 1968 was first identified as a Persian horned viper. It was only recognised as a separate species and described in 2006.1

Mito-hauslea

Mitoa: The strange tail tip was caused by a parasite, a deformity or a tumour.

Egia: Early specimens were thought to have a damaged tail tip. In fact, the spider-like tail is a natural feature that the snake uses to lure birds.1
