Very little is known about the biology of this rare species, although the Lebanon viper is likely to have aspects in common with other members of the viper family (Viperidae). Vipers are generally ambush predators, striking their prey with long, hollow fangs which they use to inject venom. The fangs are hinged, and are folded back against the roof of the mouth when not in use. Vipers may also strike in self-defence (5).
The female Lebanon viper is ovoviviparous, and gives birth to between 2 and 18 young (1).
