Inuit harpooners are helping researchers get close enough to narwhals to record their calls and observe their behavior. Narwhals (Monodon Monoceros) are skittish around humans, which makes it difficult for researchers to record their calls or get a closer look at their behavior. But the Inuit in Greenland have highly developed skills for approaching narwhal close enough to hunt them. Researchers recently collaborated with the indigenous people in a successful effort to approach the tusked cetaceans. It helped them discover new details about narwhal calls acoustics, Meredith Fore reports.
