A lucky wildebeest escaped after a huge crocodile bit down on its tail and dragged it into a river.

Fotage captured the moment the croc snatched at its prey and used its strength to pull its prey into the rapids.

Witness Kristin Torres was leading a tour along the Mara River, Tanzania, during the Great Migration.

The determined wildebeest managed to climb to its feet and wrestled its tail away from the predator and stepped away to safety.
