In this photograph taken on November 11, 2016, Indian snake-catcher Kali displays a sawscaled viper on a stick, caught in the paddy fields during scouting in the early hours of the morning at Vadanemmeli village, on the outskirts of Chennai. A small scythe, a crowbar and a bundle of canvas bags are all that Kali and Vedan carry when they venture into the fields of southern India to catch some of the world's deadliest snakes. Their skills, passed from generation to generation of the Irula tribe they belong to, are crucial for the production of anti-venom in the country with the world's highest number of deaths from snake bites. / AFP / ARUN SANKAR / TO GO WITH AFP STORY: India-health-animal-poverty, FEATURE by Claire COZENS (Photo credit should read ARUN SANKAR/AFP/Getty Images)
