National Geographic wildlife photographer Mattias Klum tells a funny story about the day a lioness got a little too close.
He was lying on the ground near her in an effort to get a good shot.
"I like the perspective, it's like, in her realm," Klum recalls, "I'm not in a platform, or in a jeep, I'm there with her. And it felt really good. Until she started walking towards me."
Filmed at a recent National Geographic event. You can buy Klum's photos here, and follow him on Twitter here.
