Why They Matter. Whales, like the narwhal, are at the top of the food chain and have an important role in the overall health of the marine environment. Like polar bears, the narwhal depends on sea ice for its existence and can be directly impacted by climate change.

How do narwhals help the Earth?
An iconic whale species will soon be aiding climate change research. Narwhals are spending more time near melting sea ice and researchers hope to exploit this new behaviour by tagging the mammals with temperature sensors to help us accurately monitor underwater sea ice melt for the first time.
What is so special about narwhal?
One of the most interesting facts about narwhals is that males of the species grow a long, spiraling tusk, which gives the whale its most distinct characteristic. Another feature that makes these whales’ appearance so unique is the lack of a dorsal fin.
What do humans use narwhals for?
Inuit people hunt the narwhal for their long tusks and their skin, an important source of vitamin C in the traditional Arctic diet.
Why are narwhals tusks important to them?
Martin Nweeia’s investigations, in combination with Inuit observations and traditional knowledge, have revealed that the tusk may be a sensory organ. Narwhals may use their tusks to detect temperature, water pressure, particle gradients, and motion.
Has anyone been killed by a narwhal?
LONDON — Queen Elizabeth II has approved a rare royal pardon for an inmate convicted of murder who used a narwhal tusk to help stop a terrorist attack in which two people were killed before the assailant was killed by the police on London Bridge.
What are three interesting facts about narwhals?
Unlike some whale species that migrate, narwhals spend their lives in the Arctic waters of Canada, Greenland, Norway and Russia.
- Narwhal live up to 50 years.
- Narwhal change colour with age.
- Their tusks are actually a tooth.
- Narwhal’s distinctive tusk are usually found on males.
- Tusks can grow as long as 10 ft.
What are baby narwhals called?
Narwhals have just one baby (called a calf ) every three years. They will stay with their mother and nurse for over a year before they grow more independent and learn to hunt on their own with the pod.
Why does a narwhal have a horn?
The horn is actually a canine front tooth that can reach as long as nine feet. But until recently scientists weren’t sure what, if any, purpose it had. Research has pinpointed many possibilities, suggesting the tusk is used as a sensory organ, helping the narwhal pick up changes in its environment.
Is a group of narwhals called a blessing?
What do you call a group of narwhals? A blessing.
Is the narwhal horn a tooth?
The narwhal tusk—most commonly found on males—is actually an enlarged tooth with sensory capability and up to 10 million nerve endings inside. Some narwhals have up to two tusks, while others have none. The spiraled tusk juts from the head and can grow as long at 10 feet.
Do narwhal tusks grow back?
But unlike their relatives, the narwhal has no “chewing” teeth, just the one tusk and an occasional backup. Interestingly enough, this second tooth can occasionally grow into a second tusk and either one is able to grow up to nine feet long.
Can you swim with narwhals?
While viewing narwhal in the wild is incredible on its own, swimming with narwhal is a bucket list experience many travellers can only dream of. While snorkeling at the floe edge, the two were welcomed by a pod of up to 60 narwhal swimming through the area!
What did Narwhals evolve from?
Traditionally, the theory of cetacean evolution was that whales were related to the Mesonychids, an extinct order of carnivorous ungulates (hoofed animals), which resembled wolves with hooves and were related to the Artiodactyls (even-toed hoofed mammals).
What are Narwhals predators?
Killer whales and polar bears have been known to attack and eat Narwhals, and at least one Greenland shark has been captured with narwhal remains in its stomach, but it remains unclear if it hunted or scavenged that meal.
