These adorable panda cubs were born at Zoo Atlanta on July 15.
Twin Panda Cubs
Twin panda cub brothers snuggle up at Zoo Atlanta, and now they have names: Mei Lun (may loon) and Mei Huan (may hwaan).
The panda twins get examined at about a month old.
Mom and Baby
The twins were born to panda mom Lun Lun.

The twins were a surprise to Zoo Atlanta's panda keepers. It is difficult to tell if a female panda is pregnant, since they typically don't cooperate with an ultrasound and most undergo a "pseudopregnancy" if they don't conceive.
