- The Narwhal is a fascinating and elusive creature that inhabit the cold waters of the Arctic. The Narwhal is a medium-sized whale and are known for their distinctive tusk, which can grow up to 10 feet in length, and their unique hunting methods. Narwhals primarily feed on fish and squid, and their diet can vary depending on the season and location.
While they are not commonly seen by humans, Narwhals play an important role in the Arctic ecosystem and are currently classified as "near threatened" on the IUCN Red List of Threatened Species due to threats such as climate change, hunting, and human activities.

I thought these were just made-up creatures from a Christmas movie for over 30 years.
Orcas are actually dolphins.
There was a guy dressed up as a narwhal in a music video that I watched. I thought that it was a mythical horned shark.
If it's a tooth, that must hurt really bad when it bumps on to something hard or when it's very cold.
Excellent! Thank you!
tusks are used to break ice so that they can breathe
That's a valid point! Thank you for adding that information. It's worth noting that while some theories suggest that narwhale tusks may have a role in breaking ice, the exact function of the tusks is still a subject of scientific debate. The breaking ice hypothesis proposes that narwhales use their tusks to create openings in the ice, allowing them to access air at the surface when other breathing holes are scarce.
However, it's important to mention that this hypothesis doesn't explain why only males (and a small number of females) have tusks while the majority of the narwhale population lacks them. If the primary purpose of the tusks were for ice-breaking, one would expect both males and females to possess them, as both genders encounter similar ice conditions.
This is why researchers continue to explore different theories to understand the function of narwhale tusks fully. It's an exciting area of study, and further research will likely shed more light on this fascinating aspect of narwhale biology. Thank you again for your input!
as we see not all narwhales have these tusks which sadly wasn't explain, so i don't know if it's only males that have them or if the whales we saw were younger.
but if only males have them it can't possibly have a huge import like echo sonar or water temperature detection because that would mean these features are only available to male or narwhales that have these tusks.
makes far more sence if they are like antlers, elephant tusks or horns... otherwiese like half the narwhale population would lack a very important organ which dosn't make much sence.
Thank you for your comment! It's true that not all narwhales have tusks, and I apologize for not providing an explanation in the video. Allow me to clarify the tusk situation.
In narwhales, it is primarily the males that possess tusks, although a small number of females may have them as well. The tusks are actually elongated canine teeth that can grow up to 10 feet long! While it was initially believed that the tusks played a role in echolocation or water temperature detection, recent studies suggest that their exact purpose is still somewhat of a mystery.
One prevailing theory is that narwhale tusks are primarily used for social interactions and mating displays among males. These impressive tusks could be a way for males to establish dominance and attract mates. As for the females and males without tusks, they rely on other means to navigate their environment and interact with their surroundings.
The comparison to antlers, elephant tusks, or horns is a valid one. These structures are also predominantly found in males of certain species and serve specific purposes such as defense, fighting, or display.
So, while not all narwhales have tusks, it doesn't necessarily mean that the absence of tusks hampers their survival or function in their ecosystem. Nature has diverse ways of equipping different individuals within a species, and narwhales are no exception. I hope this helps clarify the significance of narwhale tusks! If you have any further questions, feel free to ask.
GREAT INFO
I am interested in to narwhals because they look like a unicorn and they are my favorite animal because look like a unicorn and I love unicorn
Gods creations are all amazingly remarkable, just look at this whale..... Doesn't it make your brain freeze trying to figure out the nature of it all
Aren't these clips recycled video from the National Geographic video?
i tried to find multiple sources to get clips to explain about the Narwhal ❤
They're delicious
XOOO
Narwhals are not real
You seem to repeat yourself continuously…..
