Its head looks like other snakes in its group, Pseudocerastes. But its tail is very different! The spider-tailed horned viper has a tail that looks just like a spider. It uses this clever tail to trick and catch its food.

What is a Spider-Tailed Horned Viper?

The spider-tailed horned viper is a medium-sized snake. It is known for its unique tail. This tail has a round end with long, scale-covered parts. These parts stick out and look like the legs of a spider. The snake moves its tail in a way that makes it look like a spider crawling.

How the Viper Got Its Name

The scientific name for this snake is Pseudocerastes urarachnoides. The word "urarachnoides" comes from two Greek words. "Ura" means tail, and "arachnos" means spider. So, its name literally means "spider-tailed." This name perfectly describes its most amazing feature.

Where Does This Viper Live?

This special viper is found only in a specific part of the world. It lives in the rocky deserts and dry areas of western Iran. This region has a harsh climate. It gets very hot during the day and cold at night. The viper is well-suited to live in this tough environment.

Its Natural Habitat

The spider-tailed horned viper prefers areas with rocks and sandy soil. It often hides among rocks or in burrows. This helps it stay safe from predators. It also helps it ambush its prey. Its body color often blends in with the desert landscape. This makes it hard to spot.

How the Spider-Tailed Viper Hunts

The spider-tailed horned viper is a master of disguise. It uses its spider-like tail to hunt. This hunting method is called caudal luring. It is a very clever way to catch food.

The Clever Tail Trick

When the viper is hungry, it hides its body. It leaves only its tail exposed. It then wiggles the tail. The tail looks exactly like a spider moving. Birds, lizards, and other small animals see the "spider." They think it is an easy meal. When they get close enough to grab the "spider," the viper quickly strikes. It catches its prey before the animal knows what happened.

What the Viper Eats

The main food for the spider-tailed horned viper is birds. Birds are often attracted to what they think is a spider. The viper also eats lizards and other small desert animals. Its venom helps it quickly overpower its prey.
