Endangered frogs with unfortunate nickname go on display at zoo

An endangered amphibian nicknamed the “scrotum frog” has gone on display at a zoo as part of efforts to save the species from extinction. The Lake Titicaca frog was given the unfortunate nickname because of the saggy folds of excess skin which it uses to absorb oxygen from the water at the bottom of the lake, on the border of Bolivia and Peru. Twenty of the rare frogs have gone on show to the public for the first time at Chester Zoo, where conservationists are studying their behaviour in the hope of helping to save them from extinction.
