Terrifying FPV footage shows first-hand what it's like like to take on the world's most dangerous job - feeding hungry crocodiles their lunch.

Wearing a sports camera on his head, Panya Siangjong, 49, fed fresh meat to thousands of killer reptiles on his farm in Nakhon Pathom province, Thailand.

Crocs open their mouths and lunge at the caretaker and snap at his feet, but he casually uses the orange plastic container to bat them away.

The animals range in size from just 3ft long to adults that are around 8ft long. The larger crocs have enough power in their jaws to tear apart a human in seconds.

Even when the pieces of chicken are laid on the ground, the beasts follow their natural instincts and size up Panya.

However, none have attacked him yet, despite him working at the farm every day for more than 10 years.

'The crocodiles are smart, they know I'm the boss, so they don't attack me,' said Panya, 40, who runs the facility with his wife.

'I'm not afraid. I've become used to the crocodiles and they know me. I know how to protect myself.'

Panya credits his thick rubber boots from preventing the crocodiles from biting his ankle. He said he has also developed a technique of using the plastic container that holds the meats to push the crocodiles away.

The farmer also has a metal rod used to drag the container, that he waves at the crocs when they venture too close to him with their teeth bared.

However, he carries no other protective equipment when he ventures into the beast's concrete pools.

Panya added: 'I would not recommend people try feeding crocodiles without having a lot of experience. They are still predators and their instinct is to eat humans.'
