What colors are narwhals?
Narwhals are typically bluish-gray in color with mottled patterns. As they age, they become whiter, and some old narwhals can be nearly pure white.
Where do narwhals live?
Narwhals predominantly inhabit the icy waters of the Arctic, around Canada, Greenland, and Russia.
Are Narwhals born with horns?
No, narwhals are not born with tusks. The tusk starts to emerge when they are around 1 to 3 years old, especially in males.
What do baby narwhals look like?
Baby narwhals, or calves, have a bluish-gray color that’s darker than adults. They don’t have a prominent tusk, making them look smoother in appearance.
What do baby narwhals eat?
Baby narwhals drink their mother’s milk for the first 20 months of their life before transitioning to a diet of fish, squid, and shrimp.
Why are narwhals mysterious?
The remote and harsh Arctic habitat of narwhals makes them difficult to study. Their deep diving habits and elusive behavior add to their mystery.
Do narwhals attack humans?
There are no known instances of narwhals attacking humans. They are generally shy and keep their distance.
Do narwhals breathe air?
Yes, narwhals breathe air. They have blowholes on the tops of their heads to inhale and exhale.
Do narwhals break ice?
Narwhals don’t actively break ice. However, they can surface through thin ice using their robust skulls.
Do narwhals change color?
Yes, as narwhals age, their coloration changes from a dark bluish-gray to a lighter, almost white hue.
How do narwhals communicate with each other?
Narwhals use a series of clicks, whistles, and knocks to communicate, especially in the murky depths of the Arctic waters.
Can narwhals deafen humans?
While narwhals produce loud clicks for echolocation, there’s no evidence suggesting these sounds can deafen humans.
Do narwhals eat dolphins?
No, narwhals do not eat dolphins. Their diet consists mainly of smaller prey like fish, squid, and shrimp.
Do narwhals swim upside down?
Interestingly, narwhals have been observed swimming upside down, especially when they are skimming the seafloor for prey.
Do narwhals have dorsal fins?
No, narwhals lack a dorsal fin, which aids in navigating the icy Arctic waters.
Do narwhals eat seals?
While narwhals primarily feed on fish, squid, and shrimp, they have occasionally been observed hunting small seals.
Do narwhals have teeth?
Yes, apart from their iconic tusk, narwhals have teeth in their mouths, though they aren’t prominently used for chewing.
Do narwhals stab each other?
While their tusks might appear as weapons, narwhals don’t typically use them to stab each other. However, males may cross and rub their tusks in a behavior known as “tusking.”
Do narwhals eat orcas?
No, narwhals do not eat orcas. In fact, orcas can be predators of narwhals.
Do narwhals fight with their tusks?
Males may engage in “tusking” where they rub and cross tusks. This behavior is believed to be a form of social interaction or establishing dominance.
Do narwhals have fur?
No, narwhals do not have fur. They have thick blubber to keep them warm in cold waters.
Do narwhals have gills?

Do narwhals jump out of the water?
Unlike some marine mammals, narwhals are not known for breaching or jumping out of the water frequently.
Do narwhals eat penguins?
No, since narwhals live in the Arctic and penguins in the Antarctic, their paths never cross, and thus, narwhals do not eat penguins.
Do narwhals sleep?
Narwhals, like other cetaceans, sleep by shutting down one hemisphere of their brain at a time. This allows them to rest while still being aware of their surroundings.
Do narwhals travel in groups?
