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 long, spiral tusks of narwhals could be used by these Arctic whales to stun or even kill prey, according to wildlife researchers who have spied on these elusive creatures using drones. They ...

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 ...

Every year, a new growth layer is added to the narwhal's spiralled tusk. The individual layers act as an archive of data that reveals what and where the animal has eaten, providing a glimpse of how ...

Researchers have long debated what the 10-foot-long tooth that erupts from a narwhal’s head is actually for. Perhaps it has something to do with sexual selection, and males with longer horns attract ...

It’s got a single tooth – one that shoots straight out of its head. But this tooth isn’t used for chomping and chewing. It's more like a spear. And much like the creature itself, it's a thing of ...

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 ...
