Around 58,000 deaths in India are attributed to snake bites every year, and the Russell's viper (Daboia russelii) is responsible for the majority of these mortalities.
The saw-scaled viper (Echis carinatus) is the smallest member of the "Big Four" in India — along with Russell's viper, the common krait (Bungarus caeruleus) and the Indian cobra (Naja naja).
The banded krait (Bungarus fasciatus) is a slow mover during the day and is much more likely to bite after dark.
The king cobra (Ophiophagus hannah) is the world's longest venomous snake, measuring up to 18 feet (5.4 m), according to the Natural History Museum in London.
You could be bitten multiple times before becoming aware of the coastal taipan (Oxyuranus scutellatus), thanks to its incredible speed, according to the Australian Museum.
