Risk taker: Ronda Rousey, 31, was up to her usual daredevil tricks as she took a shark dive in Fiji with the Discovery Channel for Shark Week

She was guided by former Navy diver Paul de Gelder, who coached ‘the baddest woman on the planet’ through three rounds of survival training against the heavyweights of the sea.

He told Fox News about how he got legendary UFC fighter prepared for her close encounter.

The training led to the main event where Ronda attempted to step outside the protective cage to face one of the ocean’s ultimate predators, the mako shark.

Paul knows plenty about going face-to-face with a fearsome opponent – in 2009, he was attacked by a nine-foot bull shark in Sydney Harbor while working as an Australian Navy diver, and lost his right hand and most of his right leg.

‘This woman had never dived in her life up until we came along’, Paul told Fox News.

‘She could have very easily lost a hand or an arm. That was a very, very real moment for me.
