Watch as one unlucky impala gets caught in the jaws of a hungry crocodile, mid-jump. The distraction bought the rest of the herd time to safely cross this dam in Kruger National Park, South Africa. How thoughtful.
According to Barcroft TV, the moment was captured on camera by Rene van der Schyf, who was visiting the park with her husband.
Nature will be nature.
