Chaos theory improves understanding of Arctic narwhal behavior, with the aim of helping efforts to protect this vulnerable species. Researchers have used the mathematical equations of chaos theory to ...

Scientists were able to capture rare audio of narwhal vocalizations as several swam through a fjord in Greenland, and they discovered that these elusive whales make some familiar sounds underwater.

(CNN) — Scientists say they have the first recorded video evidence of narwhals using tusks not only to strike and manipulate fish during feeding but also engage in what appears to be playful behavior, ...

Researchers have used mathematical models based on chaos theory to analyze the movements of a pod of satellite-tagged narwhals. Around solar noon, narwhals rest nearer the surface and take deep dives.

The narwhal (Monodon monoceros), an iconic whale of remote Arctic waters, is widely known for its long, spiral tusk, which is ...

Newly published drone footage sheds light into narwhal behavior and provides the first-ever evidence of the animals engaging in play, according to a new study. Screengrab from Florida Atlantic ...

The clicking, buzzing and calling behavioral patterns of elusive East Greenland narwhals have been described thanks to in-depth recordings. The clicking, buzzing and calling behavioral patterns of ...

The cold waters of the Arctic are home to an unusual whale that you might have heard of, the narwhal. Narwhals have a long, sharp tusk that juts out of their heads. As NPR's Nell Greenfieldboyce ...

Researchers have used the mathematical equations of chaos theory to analyse the data from long-term monitoring of an electronically tagged narwhal. They have extracted previously undetected diurnal ...
