Big Four (Indian snakes)
The four venomous snake species responsible for causing the greatest number of medically significant human snake bite cases on the Indian Subcontinent (mostly in India) are sometimes collectively referred to as the Big Four. They are as follows:
- Indian cobra, Naja naja
- Common krait, Bungarus caeruleus
- Russell's viper, Daboia russelii
- Saw-scaled viper, Echis carinatus
Naja naja, the Indian cobra
Bungarus caeruleus, the common krait
Daboia russelii, Russell's viper
Echis carinatus, the saw-scaled viper
Of the Big Four, the common krait is responsible for the most snake bites, followed by Russell's viper, the saw-scaled viper, and the Indian cobra.
A polyvalent serum that effectively neutralizes the venom of all of the Big Four snakes is widely available in India, and is frequently administered to save lives.
