On the Brazilian island of Grande, 5,000 venomous snakes live here. The island is considered extremely dangerous, and these snakes can even catch birds flying in the air and then poison them to death with venom. Imagine what it would be like if you were to travel to such an extremely dangerous island.

This is the only island spearhead pit viper on Earth; also known as the golden-headed cave snake' habitat, which may be a good thing, because this reptile is considered one of the most venomous snakes in the world.
Because the island is considered extremely dangerous, the Brazilian government has banned people from traveling there, and only a few scientists come every year to study the Golden Gun-headed Cave Snake.
But there have been many explorers who have come to explore, but in the end they will only end up being bitten. So now that ordinary tourists have been banned, the Brazilian Navy occasionally visits the area.
