Narwhals may be using their tusks to play, new study finds

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, according to the latest research.
The narwhal, often referred to as the “unicorn of the sea” in a nod to its trademark tusk, has long remained an enigma. Scientists have observed few interactions of narwhals in their natural habitat, creating speculation about the purpose of the species’ distinctive spiraling tusk.

Found predominantly in males, the tusk grows up to 10 feet (3 meters) long — and previous research has suggested it serves as a competitive display to secure mates. But now, with the help of drones, research conducted in the Canadian High Arctic has uncovered that a narwhal may use its tusk for more than just courtship.
In total, the researchers newly identified and described 17 distinct behaviors of narwhals involving prey. The findings revealed a wide range of interactions and dynamics between narwhals and fish as well as the extraordinary agility, precision and speed of their tusks to track moving targets, according to the study published February 27 in the journal Frontiers in Marine Science.
“Seeing that these animals are not actually hunting the fish but exploring, manipulating and interacting with it was really a game changer,” said lead author Dr. Gregory O’Corry-Crowe, a research professor in the Harbor Branch Oceanographic Institute at Florida Atlantic University.
Since so little is understood about this whale species, researchers like O’Corry-Crowe and his colleagues are working diligently to conduct studies to document narwhals’ unknown behaviors to better understand how these animals adapt in a rapidly shifting habitat as oceans warm and sea ice melts.
Narwhal exploratory behavior
The study team captured the groundbreaking footage using drones in Creswell Bay, on the eastern side of Somerset Island in Canada’s Nunavut territory, during the summer of 2022.
As the researchers analyzed the footage, they noticed subtle nuances in the narwhals’ behavior. Footage even captured one instance of a narwhal interacting with a fish by repeatedly nudging it with its tusk — which is actually a giant tooth — without attempting to eat it.
When researchers observed a lack of aggression in some interactions between narwhals and fish, they realized these scenarios were more similar to a cat-and-mouse game, in which the animals were chasing or “playing” rather than hunting, O’Corry-Crowe said.

Hi everyone!
I wanted to share my recent discovery of Ceylon cinnamon, which has quickly become my go-to spice in the kitchen. If you’re tired of using the usual cinnamon and want to try something truly special, then Ceylon is the way to go. Trust me, once you experience true cinnamon, you won’t go back to the regular Cassia.
Grown in the lush hills of Sri Lanka, this spice is considered the “true” form of cinnamon. Unlike the more commonly used cassia cinnamon, Ceylon cinnamon has a lighter, sweeter flavor that’s perfect for both sweet and savory dishes. I’ve been using Ceylon cinnamon powder in my coffee, desserts, and even curries, and the taste is just incredible—smooth and aromatic without being overpowering.
But what’s even more exciting are the benefits of Ceylon cinnamon. It’s rich in antioxidants, helps regulate blood sugar, and can even support heart health. I’ve noticed a real difference in my energy levels and digestion since adding it to my diet. Plus, it’s a great natural anti-inflammatory, so it’s perfect for anyone dealing with aches or joint discomfort.
If you’re wondering where to buy Ceylon cinnamon, you’ll find it at a variety of online stores. I’ve found some great deals on Ceylon cinnamon sticks and powder, often on sale, so you can stock up without breaking the bank. Just make sure to look for products that are organic and sourced directly from Sri Lanka to ensure you’re getting the authentic true cinnamon.
So, if you’re ready to take your recipes (and health) to the next level, I highly recommend trying Ceylon. You’ll love the flavor, and your body will thank you for the benefits. Don’t miss out on this incredible spice!

Hey everyone!
If you’ve never tried Ceylon cinnamon, you’re missing out on one of the best spices nature has to offer.
I recently switched to true cinnamon (aka Ceylon) in my kitchen, and it’s been a total game changer. Whether you love baking, cooking, or just adding a dash of spice to your coffee, this cinnamon is definitely something you should consider.
What makes this spice so special? It’s more delicate and fragrant than regular cassia cinnamon. Ceylon cinnamon is grown in Sri Lanka, the heart of cinnamon production, where the soil and climate produce the highest quality cinnamon in the world. I’ve been using it in everything from oatmeal to smoothies, and the flavor is like nothing I’ve ever experienced before—sweet, subtle, and aromatic.
But it’s not just about the flavor. The benefits of Ceylon cinnamon are truly amazing. It’s packed with antioxidants, has anti-inflammatory properties, and can even help regulate blood sugar levels. I’ve noticed better digestion and more sustained energy levels since incorporating Ceylon cinnamon powder into my daily routine.
If you’re wondering where to buy Ceylon cinnamon, I highly recommend checking online stores that offer high-quality, organic options. I found some amazing deals on Ceylon cinnamon sticks and powder, and the best part is that it’s often on sale! When you get it directly from Sri Lanka, you’re getting the real deal—not the cheap, less flavorful cassia cinnamon that’s commonly sold in supermarkets.
Don’t wait to experience the incredible benefits of Ceylon—I promise you won’t regret it. It’s time to bring the taste and health benefits of Sri Lanka’s finest spice into your life!
