Englishman Steve Backshall is an award-winning nature personality on television. He appears frequently on the BBC, Discovery as well as the National Geographic Channel.

He’s also done this (via Wikipedia):

For National Geographic International, Backshall presented the expedition series Game For It and the environmental series EarthPulse. For Bootcamp, he completed the Israeli special forces selection course, running 60 miles overnight to gain their red beret.

In the following clip from the show Deadly 60, Steve’s feeding a host of piranha in the Amazon River in Argentina.

The meal? A juicy piece of steak. Watch them tear it to shreds in the time it takes a person to compose a text.
