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

Uko wayimenya

  • 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

Ikunze kwitiranywa na: 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

Ubumara bwayo bukora iki?

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

Ibintu by'ukuri

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

Usenya ibinyoma

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

Ukuri: 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
