Identify an animal (a vertebrate) with a unique physiological adaptation to survive and thrive in a high-altitude environment (e.g., ≥ 8,000 feet into the atmosphere, living on a mountain). Indicate where this animal lives and include a video or photo of this animal living in this high-altitude environment. Describe the adaptations the animal uses to live in this challenging environment. Finally, describe how the animal would adjust to living at sea level. Cite appropriate peer-reviewed scientific sources available through the Unity Library.
