Po, the only panda born alive at a U.S. zoo last year, made his debut yesterday at Zoo Atlanta. Po, who was named by actor Jack Black in recognition of how he "helped to bring the importance of saving this species to a new generation of conservationists," is the third cub born to Atlanta's female panda Lun Lun. He's not yet able to walk, but that's normal at this stage of development.

Watch Po lounge around with Lun Lun in the video below, which first aired on the BCC March 15, 2011.
