#sheddaquarium

Two male #beluga at the #sheddaquarium play with a rubber ring #enrichment item. They spent easily half an hour dragging around their pool, balancing it on their rostrums and diving through it. In the first photo, you can see how flexible their necks are; the cervical vertebrae in #belugawhales are not fused (unlike most #cetaceans ) which is likely an adaptation that helps them maneuver under ice. #whales #belugawhale #adaptation #animaladaptations #environmentalenrichment (at Shedd Aquarium)
