Tomorrow morning the Philadelphia Zoo and its guests will gather to celebrate the birthday of Coldilocks the polar bear. The old lady is turning the big 3-5, with a cake and a birthday song.

Coldilocks is celebrating the extra year for many reasons — the most important of which is bragging rights. She is the oldest polar bear in the United States, far surpassing the 23-year average lifespan of polar bears in zoos. She’s been living in Philadelphia for most of her life, three decades. Like many animals the Zoo keeps, polar bears have been classified “vulnerable” due to increased threats from climate change and the resulting shrinking of polar ice.

There will be no shrinking at the Zoo tomorrow, though. Coldilocks will surely revel in all the attention — and especially that cake. If you want to join in the festivities, show up at the polar bear tank at 10:30 am.

For now, enjoy a few more photos of Coldilocks from the Philadelphia Zoo. Let’s try to guess some of her anti-aging secrets. Girls doesn’t look a day over 29.


Rolling around in the cold keeps your skin nice an tight (read: fewer wrinkles). All that fur does a good job of hiding age spots, too. Ask any scruffy-faced hipster.


The “drink plenty of water” rule applies to polar bears, too. It’s hands-down the best way to keep that skin hydrated. Slurp!
