You couldn't pay me enough money to take a tour through musty rivers! But a Brazilian tour guide was taking a boat full of tourist through the Araguaia River when he spotted an anaconda under water.
He tried to film the snake but then realized the snake was getting ready to attack. Luckily, the snake didn't puncture his skin and the tour guide was able to laugh it off.
But still, very scary... YOU WOULD NEVER CATCH ME ON A TOUR LIKE THIS.
