Russell’s Viper Profile and Information

Russell’s Viper

Russell’s Viper which has the scientific name, Daboia russelii, belong to the family of venomous snakes called Viperidae which is native to the subcontinent of India.

The name Russell’s Viper was given in honor of Patrick Russell who was the first to write about it in 1796, in his work “An account of Indian serpents, collected on the Coromandel coast”.

It is a common belief among herpetologists that another specie of snake known as Gongylophis Conicus, a rough-scaled sand boa has come to mimic the appearance of D. russelii, this is because D. russelii has a dreadful reputation within its natural environment and it has become so successful as a species.

Taking a superficial look at the rough-scaled sand boa, we will see that its color pattern resembles that of D. russelii, although it causes no harm.
