"So today we have Laerke, our three-year-old polar bear female, and she's anesthetized for her routine annual physical exam. We're looking for any kind of lumps, bumps, masses and large lymph nodes, anything that would be an indication of ill health. But we didn't find any of that. She is in optimal condition.”
