Giant bullfrogs plague France
France is being overrun by a plague of giant bullfrogs.
Wildlife experts say the Californian frogs are threatening to disrupt the ecology of south-west France by eating lizards, fish and small birds.
It is illegal to import the bullfrogs, but colonies have developed after a small number were released as a joke in a private pond in the early 1980s.
Environmental officials are trying to find a way to get rid of the animals after previous efforts to destroy them using electric poles proved unsuccessful.
Britain discovered its first breeding colony of giant American bullfrogs in East Sussex last year.
