After officials drained a toxic, malaria-filled swamp in Israel’s Hula Valley back in the 1950s, several species, including the Hula Frog were wiped out. It was the first amphibian ever to be declared extinct. But, almost 60 years later, researchers came across a male adult specimen on a routine patrol.
Not only that, but it’s since been discovered that the Hula Frog is the only surviving member of a genus of frogs called Latonia.
