Litsemba, behind, 11 months pregnant with her third offspring, romps in the sun in the Expedition Tanzania exhibit with Sundzu, her 2-year-old, at the Reid Park Zoo, 3400 Zoo Court, in Tucson, Ariz. Litsemba, or "Semba" for short, is expected to give birth sometime between the end of June and beginning of August next year. It marks the first-ever elephant pregnancy for the zoo, said education coordinator Vivian VanPeenen. Photo by Mike Christy / Arizona Daily Star
