Lying on her back, enormous paws in the air, Laerke the polar bear is being given her annual medical exam. It takes a good half-dozen veterinary staff to turn her over. The recent exam at Point Defiance Zoo & Aquarium in Tacoma, Washington, provided encouraging results for 3-year-old Laerke, who has been living in the U.S. state with her twin sister since June 2023 when they moved from the Detroit Zoo.
