A polar-bear cub born on New Year's Day - and then rejected by her mother - is in a stable condition, say staff at Penglai Ocean and Polar Region World in China.
The bottle-fed female weighs just over half a kilogram. She has been suffering from problems with her digestive, respiratory and nervous systems since her Russian-born parents rejected her.
The cub also struggled with severe malnutrition because of the lack of breast-feeding.
According to aquarium staff, the cub - which is still in an incubator - is no longer in critical condition and will be ready for her first public appearance in six months' time.
In the wild, polar bears generally live into their early teens. In captivity, they can reach at least 35-years-old.
The polar bear is the world's largest land predator, according to the US Fish and Wildlife service.
There are estimated to be 20,000 to 25,000 polar bears in the wild.
