Snakes (specifically the Big Four in India: Common Krait, Indian Cobra, Russell's Viper, Saw-scaled Viper)

India's "Big Four" venomous snakes—the Common Krait, Indian Cobra, Russell's Viper, and Saw-scaled Viper—are responsible for the majority of serious snakebite incidents in South Asia. Each possesses potent neurotoxic or hemotoxic venom capable of causing paralysis, tissue damage, or fatal hemorrhaging. Their adaptability to human environments makes them particularly dangerous, though they typically strike only when threatened.
