This past weekend, SFGate featured a story on longtime California Academy of Sciences resident Pierre the Penguin, who turned 31 last month (February 16).
Pierre's claim to fame was in 2007, when senior biologist Pam Schaller, wetsuit manufacturer Oceanic Worldwide and children's costume seamstress Celeste Angel desiged a custom made wetsuit for him in 2007.

Here's the 2008 local TV story on Pierre from KRON-TV:
Pierre eventually grew his feathers back and no longer wears the wetsuit. He now lives happily ever after with his colony of followers and his woman, Homey.
