Malpolon monspessulanus, commonly known as the Montpellier snake, is a species of mildly venomous rear-fanged colubrids. It is up to 2.00 metres (7 ft) long and may weigh up to 1.5 kilograms (3 lb). Although it is venomous, only a few cases of envenomation of humans are known, one of which occurred when a finger was inserted into the snake's mouth. The Montpellier snake is not a dangerous snake for humans. The rear fangs reduce the possibility of venom injection, and the venom is of low toxicity. Venom injections are possible in bites of big individuals. The venom is not very dangerous; symptomatic treatment suffices to treat an envenomation.The unthreatening nature of the snake, along with its relatively mild persecution by man, has made it one of the more common species throughout its range, even in areas occupied by humans.
