When keepers at Kobe Municipal Oji Zoo knew 12-year-old Tan Tans due date was approaching they must have expected a harder days work than this.  

Panda births are normally a traumatic process but Tan Tan made it look easy when she gave birth to a 25cm-long cub on Tuesday afternoon.

The sex of the cub is yet to be determined by zookeepers and they are inviting members of the public to suggest a name for the 100g baby panda.

Tan Tan, who like most pandas was reluctant to get it on with mate Ko Ko, was artificially inseminated at the zoo and it is the first time a panda has given birth their.
