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

Hello arano

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

It eats birds, including the Isabelline shrike and several warbler species. It waves the tip of its tail in a figure-of-eight pattern to lure insect-eating birds within striking range.1

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

Ina heewi waylondireede e: 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

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

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

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

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

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

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

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

Feññinoowo fenaande

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

Goonga: 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
