Pseudocerastes is a genus of vipers endemic to the Middle East and Asia. It was originally created as a monotypic genus in 1896 by Boulenger for the species Pseudocerastes persicus, [1] but three species are now recognised: the spider-tailed horned viper (P. urarachnoides); Persian horned viper (P. persicus) and Field's horned viper (P. fieldi). [2] [3] Like all other vipers, the members of this genus are venomous.

Contents

Pseudocerastes are often referred to as false-horned vipers [2] because of the horn-like structures above their eyes that are made up of numerous small scales. This is in contrast to the "true" horned viper, Cerastes cerastes , which has similar supraorbital "horns", each consisting of a single elongated scale. [4]

Taxonomy

In 2006, Bostanchi, Anderson, Kami and Papenfuss described a new species: P. urarachnoides. It is found in the Zagros Mountains of western Iran and is described as having the most elaborate tail ornamentation of any snake yet described, save for the rattlesnakes, Crotalus and Sistrurus . [5]

P. fieldi and P. persicus were once regarded as two subspecies of the same species, but further studies on the snakes' morphology, molecular structure and toxicology determined that they are in fact separate species. [2] [6]

Caudal luring is a form of aggressive mimicry characterized by the waving or wriggling of the predator's tail to attract prey. This movement attracts small animals who mistake the tail for a small worm or other small animal. When the animal approaches to prey on the worm-like tail, the predator will strike. This behavior has been recorded in snakes, sharks, and eels.
