Disclaimer: This thread has nothing to do with Human snakes and is only about venomous snakes found in Pakistan. I have used the research material available in open domain and made collage of snakes for identification Purpose.
Snake's hypnotic eyes and implacable mouth invokes mystery, fascination, horror and have inspired myths, religions, cults, literature and legends since ancient times. While the snakes have always been part of subcontinent folklore, legends and scripture however the first known documented work was made by a Belgian British George Albert Boulenger in 1890, the work was known as “The Fauna of British India”. The book is the first work which presented the known herpetofauna of the subcontinent in a volume. Its part dealing with snakes contributed to the proper understanding of the different species, their ways and life style. Publication of this work instigated general interest in ophidian study. Malcolm Arthur Smith (1943) revised Boulenger's work to encompass species since described, included new data about the distribution of several species, correcting several old records. Moreover, it included data on habits, ecology and reproduction of almost all known species.
Several works have been since done on snakes in Pakistan (Minton, 1962, 1966; Mertens, 1969, 1970).
The most recent and comprehensive work since then has been done by Muhammad Sharif Khan, an internationally acclaimed Pakistani herpetologist. His work is known as “A GUIDE TO THE SNAKES OF PAKISTAN” and is available at academia.

Unfortunately there are no official conservation schemes in Pakistan for these majestic creatures and nothing is being done by WWF Pakistan as well. Due to intrinsic fear of snakes and unawareness, people tend to kill snakes which sometimes dangerously affects the ecosystem.
