Lizzie took centre stage at a photocall just over a week after she was born at the zoo.

She is the third infant to be produced by her mother Leah, aged eight, and her father Fred, 26.

Lizzie weighed seven kilos at birth and has been gaining a steady two kilos every day since then.

Both mother and baby were said to be doing well.

Head keeper Darren McGarry said he had found the infant when he went to check on her mother.

"All the keepers were very excited," he admitted.

"She certainly helps to brighten up a cold, dark winter's morning - she's a real ray of sunshine."

Edinburgh Zoo is part of a European conservation breeding programme for pygmy hippos.

The species is an endangered species in its native Africa.
