Snakes in Brazil

Brazil has several venomous snake species, the deadliest among the lot being the golden lancehead endemic to Brazil’s famous Snake Island, also known as the Ilha da Queimada Grande. The island is also home to other deadly snake species, estimated at around 4 30,000. However, recent studies suggest the numbers to be a little lower than before.

The Amazon rainforest, 60% of which lies within Brazil, also has its share of snakes. The species dwelling here includes the boa constrictor, rainbow boa, green anaconda, and yellow anaconda. The green anaconda, mainly inhabiting the Amazon basin, is Brazil’s and the world’s largest snake that can measure as much as 29 feet, weighing over 550 pounds. The penis snake, not a snake but an amphibian species rarely found, has been dwelling in Brazil since 2012. People saw it when a portion of the Madeira river was being drained for a hydroelectric project.
