Narwhals
Narwhals live in Arctic waters and are famous for the male's sharp, long, frontward-projecting tusk. The Inuit culture of Canada and Greenland revolves around hunting and harvesting narwhals. Contributors therefore ask and answer questions that range from the specifics of narwhal activities and appearance to their particular usefulness for the Inuit people.

How many haploids are there in a narwhal?
Narwhals, like most mammals, have a diploid chromosome number of 36. This means they have 18 pairs of chromosomes, with one set inherited from each parent. Therefore, a narwhal has 36 haploid chromosomes.
Can climate change effect narwhals?
Yes, climate change can affect narwhals by impacting their Arctic habitat through sea ice loss, changing prey distribution, and increasing industrial activities in the region. These changes can disrupt their feeding and breeding patterns, making it harder for them to survive in a rapidly changing environment.
A narwhal moves by a combination of steering, and emitting and evaluating sounds. Steering is accomplished by the combined, coordinated work of the tail and of the upturned tips of the flippers. Emitting sound is accomplished by the combined, coordinated work of vocalizations and processing by the head and possibly the tusk. The tusk also may play a critical role in identifying appropriate underwater pressures and temperatures in which to swim.
What can kids do to save the Narwhal?
Kids can give money to the Save The Narwhal project that money will help keep the Marshal from coming extinct.
How do narwhals protect themselves?
They use echo-location to find their way away, or in dire circumstances (like protecting their young) they will use echolocation to stun their attacker.
Humans and their boats have been attacked by Narwhals because they are perceived as predators (which they often have been).
Narwhals do indeed use echolocation, like dolphins, and their sensitive horns to maneuver in the ocean
Are female narwhal bones the same as male narwhal bones?
are female narwhal bones the same as male narwhal bones
No. You can only own a narwhal if your a zoo or an aquarium. But they need a specail permit
It is not legal to own any whale unless you are an aquarium or zoo and have the necessary permits and facilities to hold such an animal.
When do bucks start growing horns?
Bucks will start growing their antlers in early spring. They will be covered in "felt" and be quite soft and easily broken. Around late fall they will then solidify into a bone like tissue and stop growing. The bucks will then "rub" the felt off to reveal the solid antlers and mating season starts! :)
Do both narwhals parents stay with their young?
Nope, only one parent stays with the young, and that's the mother.
Narwhals, like other marine mammals, excrete urine through their kidneys. The urine is released into the surrounding water through the urethra. This process helps to maintain their body’s fluid balance and eliminate waste while living in a saline environment. The urine is typically diluted in the ocean, making it less noticeable.
How many narwhals can be hunted in the regions of Europe per annum?
In Europe, the hunting of narwhals is highly regulated, primarily due to their vulnerable status and international protections under the Marine Mammal Protection Act and the Convention on International Trade in Endangered Species (CITES). As of now, there is no legal hunting of narwhals in European countries, as these animals are primarily found in Arctic regions of Canada and Greenland. Therefore, any hunting quotas would depend on regulations set by those regions rather than Europe as a whole.
