Scientists have made a discovery about a rare viper. The viper has a unique feature on its tail that resembles a plump spider. This feature is used to lure predators, which then become the viper's prey. The viper's body is covered in bumps and has horn-like features on its head.

The discovery was made after examining a specimen collected in 1968. At the time, the spider-like feature on the tail was overlooked.

Further details about this unusual viper and its habits are available from the source, including information about its habitat and behavior.
