I'm saddened to report that one of the giraffes at the San Francisco Zoo passed away at 12:15 p.m. yesterday, suffering from cardiac and respiratory arrest. Gezi (mama to that cutie pie, Barbro, we saw born back in February) was one of six long-necked creatures in the city. The necropsy results came in Wednesday afternoon, and the zoo just announced that the mom to Terrance (born on May 18, 2006) and recent babe, Barbro, (Feb. 25) was in her first trimester at the time of death! According to local news reports, it also showed Gezi had enlarged lymph nodes, inflammation within her gastrointestinal tract, and more than 100 "suspicious black masses" throughout her body. Although the zoo did not elaborate what those masses were, they will perform more tests to confirm the exact cause of death of this pregnant giraffe. In the meantime, the other giraffes (one adult male, two adult females, and two calves, one male, and one female) remain in good condition.
