The golden lancehead is an extremely venomous pit viper that lives only on one small Brazilian island, Ilha da Queimada Grande. It is one of the most venomous snakes in Latin America. Because the island is uninhabited and closed to visitors, it is very unlikely that people will ever meet one.1

The island has forest, clearings and shrubs, and a mild climate that stays between 18 °C and just over 22 °C. The rocky terrain makes the island hard to reach, and no humans or other mammals live there. The snake hunts in trees and shelters in leaf litter or rock crevices.1

Adults mostly eat perching birds and also lizards, and may sometimes eat other golden lanceheads. After biting prey, it keeps the animal in its mouth instead of releasing it and tracking it, which is thought to suit hunting birds.1

Its venom is adapted to the animals of the island, mainly reptiles, arthropods and migrating birds, so it works better on these than on mammals. Chemical analysis suggests it is five times as potent as the venom of B. jararaca and is the fastest-acting venom in the genus Bothrops. Its venom becomes more potent as the snake matures. Effects reported in envenomations include swelling, pain, nausea, vomiting, blood blisters, bruising, bleeding into the gut and brain, kidney failure and severe muscle damage.1

No official report of a human bite from this species has been made, because the island is uninhabited. Other lanceheads cause more human deaths than any other group of snakes in North or South America. One researcher reports four human envenomations by this species, three of which were fatal. For lanceheads in general, the mortality rate is 0.5 to 3.0% with treatment and 7.0% without it.1
