Wildlife presenter Steve Backshall has revealed how he was bitten by a crocodile while filming a children's BBC series.
The naturalist, 37, was wading through the mud looking for an anaconda - a giant snake - when he was attacked.
Backshall, who is about to front BBC1's Lost Land Of The Tiger, told TV Times: "I was bitten by a crocodile earlier this year.
"I was working in the swamps in northern Argentina, filming Deadly 60 (a series for the BBC children's strand CBBC about the world's most dangerous creatures).
"The director thought he spotted a big anaconda, which was the snake we were looking for, so I got off my horse and waded through the mud trying to find this thing.
"My foot hit what I thought was a branch and I remember thinking, 'There are no trees around here!'."
Backshall added: "With that, this crocodile swung round, bit me on the calf and then swam away. I needed 10 stitches and it was a right mess, but it's healing into a nice scar now."
The adventurer, who also broke two vertebrae in his back while rock-climbing in the Forest of Dean, Gloucestershire, two years ago, presented Lost Land Of The Volcano and Lost Land of The Jaguar and the long-running CBBC series The Really Wild Show.
In Lost Land Of The Tiger, a three-part series, he travels to Bhutan to prove that the area is inhabited by tigers, as finding the group is of huge importance for the survival of the species.
