Ten Deadliest Snakes with Nigel Marven

Wildlife adventurer Nigel Marven counts down his choices for the ten deadliest snakes in the US, South Africa and Costa Rica. To compile the lists he goes anywhere and everywhere - pristine jungles, rocky deserts, rubbish dumps or city wasteland - and to see pygmy rattlers he even explores Cape Canaveral. Along the way Marven has close encounters with infamous snakes, among them cobras, bushmasters, rattlesnakes, and mambas, so viewers can see the remarkable behaviours and powerful strikes of these unique and phenomenal creatures.
