At 12 days old, a baby panda in San Diego Zoo is starting to get its trademark black-and-white markings.

The cub, who hasn't been named, was captured by the zoo's 'panda cam' on Thursday.

The mother and the cub will remain out of the public gaze for four to five months while the cub grows.

Researchers say in addition to the color markings, the baby is also making "loud vocalizations" - a sign of good health.

The sex of the cub will not be known until staff have a chance to examine the cub, which is expected to happen in approximately two months.

The giant pandas are on loan to the San Diego Zoo from the People's Republic of China.
