Extraordinary footage of a crocodile letting go of an impala after catching it in a river in Etosha National Park in Namibia.<br /><br />The video, shot on September 12, shows the impala running away as soon as the reptile opens its jaw. <br /><br />"A pack of wild dogs chased an impala to a river and a crocodile was able to catch it, but because the crocodile was out of its element it wasn't able to do a proper death roll to tear the impala into pieces, and so decided to let it go," the filmer wrote.
