A species of frog that was recently rediscovered after being declared extinct has been reclassified as a "living fossil".
Israel's Hula painted frog had not been seen for nearly 60 years, but in 2011 one was found lurking in a patch of swampy undergrowth.
Tests have revealed that the frog belongs to a group of amphibians that died out 15,000 years ago.
