- The vertebrae in a beluga’s neck is not fused together, giving it the unusual ability to turn its head up, down and side-to-side.
- Threats to beluga whales include climate change, hunting, oil and gas development, and industrial and urban pollution. Polar bears and killer whales are known predators of belugas throughout their Arctic range.
