"
Ilha da Queimada Grande, also known as
Snake Island, is an island off the coast of Brazil in the
Atlantic Ocean. It is administered as part of the municipality of
Itanhaém in the
State of São Paulo. The island is small in size, only 43 hectares (106 acres), and has a temperate climate. The island's terrain varies considerably, ranging from bare rock to rainforest."
"The island was the only home of the
critically endangered, venomous
Bothrops insularis (golden lancehead
pit viper), which has a diet of birds. The snakes became trapped on the island when
rising sea levels covered up the land that connected it to the mainland. The ensuing
selection pressure allowed the snakes to adapt to their new environment, increasing rapidly in population and rendering the island dangerous to public visitation.
Queimada Grande is closed to the public in order to protect both people and the snake population; access is only available to the
Brazilian Navy and selected researchers vetted by the
Chico Mendes Institute for Biodiversity Conservation, the Brazilian federal conservation unit.

Apparently there is no known antidote to a bite from a Golden Lancehead.
