A new girl at the San Francisco Zoo made her debut today: Martha, an 11-year-old Siberian Tiger, has joined the lineup of big cats out on Sloat Blvd. Like so many fierce women in San Francisco, Martha is not from here - she was born in captivity at the Indianapolis Zoo in 2000 and spent some time lounging around the enclosures of Omaha, Nebraska's Henry Doorly Zoo before finally finding her way to the Zoo by the ocean in the city by the bay.

Martha fills a gap left after the infamous Tatiana mauled a visitor on Christmas Day in 2007 and Tony, the Zoo's last Siberian tiger, was put down last summer. She also used to go by the name "Shasta", so give her some time to adjust to the new digs. [BCN/Appeal]
