Narwhal tusks have intrigued humans for ages. These long, spiraled tusks can grow up to ten feet and were once thought to belong to mythical creatures like unicorns. In fact, they inspired stories like Jules Verne’s “Twenty Thousand Leagues Under the Sea.”
Despite their fame, scientists didn’t fully understand how narwhals used their tusks. These tusks, which are actually elongated teeth mostly seen in male narwhals, are known for playing a big role in mating rituals. However, other potential uses remained a mystery until recently.
A recent study published in Frontiers in Marine Science revealed new insights into how narwhals interact with their environment. Researchers from the US and Canada used drones to capture unique footage of narwhals using their tusks in various ways for the first time.
Greg O’Corry-Crowe, a lead researcher, explained, “Narwhals demonstrate ‘tusking,’ where they lift their tusks out of the water and cross them. This might be a way to show off to potential mates or gauge rivals. But now we see that tusks also play roles in foraging and even playtime.”
During their observations, researchers identified 17 different behaviors, many involving interaction with nearby fish. Remarkably, the narwhals used their tusks playfully—tapping, nudging, and flipping fish without the intent to eat them. This behavior suggests they enjoy exploring their environment, almost like a game.
When it came time to hunt, however, the narwhals revealed a different side. They used their tusks aggressively, delivering swift, powerful strikes to capture fish. Sometimes, they even used their tusks to fend off scavengers like seagulls.
Even with these long tusks, narwhals are incredibly skilled. The researchers noted their impressive agility, allowing them to track fish deftly. They could perform rapid turns, completing 360-degree spins in just three seconds, showcasing their incredible maneuverability.
Social interactions among narwhals also came to light during this study. Some behaviors seemed competitive, with one whale blocking another from reaching a group of fish. Others appeared to be more about communication and socializing.
These interactions might be crucial as narwhals adapt to changing Arctic conditions due to climate change. Understanding their behavior and social dynamics could help researchers learn how these fascinating creatures will cope with their shifting environment.
Incorporating both playful exploration and serious hunting, narwhals demonstrate a variety of fascinating behaviors shaped by their habitat and social structures.
