A Chinese zoo's supposed "African lion" was exposed as a fraud when the dog used as a substitute started barking.
The zoo in the central province of Henan, replaced exotic exhibits with common species, according to a state-run newspaper.
It quoted a mother who was visiting the zoo to show her son the different sounds animals made; but he pointed out that the animal in the cage labelled African lion, was barking.
The beast was in fact a Tibetan mastiff, a large and long-haired breed of dog.
Other species housed incorrectly included a white fox in a leopard's den, and another dog in a wolf pen.
