This terrifying video shows what it looks like to be eaten by vultures

If you cart a dead wildebeest to the Serengeti and leave it there, it won't be long before the vultures come to scavenge.

And if you put a camera inside said carcass, you'll be able to see, firsthand, what it looks like to get picked apart by these frightening birds.

And lucky you! National Geographic just released the video of this exact premise.

While vultures - and this video - are terrifying, they're actually extremely important scavengers in the food chain and ecosystems.

The highly corrosive acid in their stomach allows them to eat and dispose of rotting animal carcasses, which can harbor diseases that are deadly to other animals, such as anthrax, cholera, and rabies.

By picking dead animals to the bone, they act as natural sanitation workers by cleaning up the environment and preventing the spread of whatever diseases the animals may have been infected with.

But sadly, vulture populations are declining in some parts of the world, especially in Africa. In the last 30 years, National Geographic reports, eight species of vulture in Africa have declined by a staggering 62%.

They're increasingly being poisoned by eating carcasses laced with pesticides, or are getting electrocuted by power lines or caught in wind turbines. They're even hunted by witch doctors who believe their brains harbor magical powers.
