Narwhals have existed on Earth for approximately 500,000 years, with their lineage dating back even further to earlier cetaceans. They are part of the family Monodontidae, which also includes belugas, and are well-adapted to life in the Arctic waters. Their unique tusk, which is an elongated tooth, has been a subject of fascination and study. Despite their long history, narwhals face threats from climate change and human activities.
