Why the Brazilian Navy keeps going to an island filled with deadly snakes
Just 21 miles off the idyllic coast of Brazil sits Ilha da Queimada Grande, also known as "Snake Island." It's said that on every two steps of this 110-acre island is a golden lancehead, the deadliest snake in the world. Years of isolation on a bird migration path required that these snakes adapt an extremely quick-acting and lethal venom. With no predators or competition, the snakes have been left to enhance their camouflage, their venom, and their insane jump.
