The Golden Lancehead snake

The golden lancehead snake (Latin name: Bothrops insularis) is one of the most dangerous snakes in the world.

It gets its common name from the golden color of the underbelly grows to about a length of 28 inches but some snakes have been found that have grown to 46 inches. It is thought that there are between 2,000 to 4,000 golden lancehead vipers on snake island.

What happens if you get bit?

The venom of this most dangerous animal is said to melt human flesh and one bite can cause kidney failure, intestinal bleeding, brain hemorrhaging, and can be fatal within one hour of being bitten.

What do the Golden Lancehead snakes eat?

The only things the snakes have to eat are birds that land on the island. The golden lancehead snake has evolved to climb and wait in trees, to drop on birds that land nearby.

The snakes have no predators so they rapidly reproduce. Because there are so many snakes on one island there is fierce competition for resources. Some estimates have one snake to every square meter of the island.

Do the snakes have any enemies?

Believe it or not, there are poachers who come to the island at night to steal away some of the snakes. On the black market, the snakes can be worth anywhere from 10,000 to 30,000 US Dollars. The only people who are legally permitted on the island are research teams to collect data and samples.
