This little baby bison looks like it would be no match for a hungry wolf on the prowl at Yellowstone National Park.
But looks can be deceiving.
Separated from his mother during a river crossing and stranded on a small gravel island, the one-week-old bison becomes the target of a hungry wolf.
The wolf goes in for the kill, trying to use its powerful jaws to rip open the little bison's throat -- but this baby has some aikido moves in store for the predator.
Watch what happens in the clip above, from the National Geographic show "America's National Parks: Yellowstone."
