Narwhals

One achievement that makes narwhals quite unusual is their deep diving abilities. In fact, they are the perpetrators of the deepest known dives by marine mammals. They easily dive down 800 meters/2,400 feet, at least 15 times a day. They even have been known to dive 1,500 meters/4,500 feet downwards, and to stay down at almost half an hour at a time.

The narwhal is so special because it is one of the few aquatic mammals with horns. They are an important part of Inuit culture and many people used to think that the horn of the narwhal was actually the horn of the legendary unicorn. Also, scientists are unsure exactly what their horn is for so that is slightly shrouded in mystery. But decide for yourself. Hope this answers your question.

Answer #1 They hunt them for their tusks. Answer #2 by Ginezumi Humans affect narwhals by hunting, competing for their food sources, and cluttering and polluting their Arctic environment. The Inuits of Canada and Greenland hunt narwhals for food, shelter, and tools. Other hunters kill the narwhal just to take and sell the precious, valuable tusk. Humans compete with narwhals for food sources. Narwhals are picky eaters; and prefer cod, halibut, shrimp, and squid. This aquatic fare also appeals to humans, as food and as subjects of research study. Humans also impact the narwhal environment. They clutter narwhal sea routes with surface and underwater vessels and scientific equipment. They pollute the narwhal's Arctic habitat with emissions and waste from equipment and vehicles. Likewise is the narwhal's Arctic habitat sullied by global warming, whose natural causes are worsened by human inputs to warming temperatures and waters, melting ice, and impacted marine life. For example, narwhals have specific feeding and living conditions to meet. Ice formations and marine life need certain temperature, salinity and pressure levels to abound or perish.

Answer #1 by Mediatech Narwhal are mammals, so they do not lay eggs. Answer #2 by Ginezumi Hunters want narwhal body parts if they seek food, and narwhal tusks if they seek profit. The narwhal has a long, curved tusk that projects frontwards out through the mouth. Inuit hunters generally are interested in narwhal body parts as sources of food. Non-Inuit hunters generally aren't interested in narwhal body parts as food. They seek the narwhal's tusk.

Narwhals sleep in ice crevices and in pods. They're able to shut half of their bodies down by shutting down one eye and the associated side of the brain, and keeping open the other eye and keeping going the other side of the brain. They're safest doing their 50% shutdown when they're hidden safely away in crevices from predators, and when they're traveling groupies in pods of 10-100.

Orca whales are the narwhals' greatest natural predators. Narwhals avoid the orcas by staying in the cracks between glaciers in the winter. Orca whales are unable to stay there because they are too big to fit, and because they have dorsal fins, which hinder their ability to squeeze through tight spaces. The narwhal has no dorsal fin.

The common human (homo sapien sapien) is also an enemy of the narwhal, because humans hunt the narwhal for food and for its ivory. Powdered narwhal tusk used to be sold as "unicorn horn" and was thought to be a sort of cure-all medicine, even holding possibly magical properties. Obviously we now know those statements to be false. Still, there are communities in Norway and such that rely on narwhal meat, sinew, blubber, and tusk to survive.

A narwhal stands out in a crowd because of its frontwards-projecting, braided tusk. This tusk-toting mammal is a large-sized, mottled color resident of Arctic waters. Narwhal populations may be found off arctic Canada and Russia, western Greenland, Iceland, and the polar islands off Scotland. They migrate between summer and winter feeding stations. The winter feeding stations tend to require deeper dives than the shallower feeding possibilities of summer. In addition to its specific geographic range, the narwhal also has a particular diet. There are certain fishes that it prefers: Arctic and polar cod, Gonatus squid, Greenland halibut, and shrimp. But it also is willing to accept as prey wolffish and capelin. With such special demands, the narwhal especially is vulnerableto climate and environmental changes. In fact, such changes may be even more threatening than traditional predation by hunters, killer whales [Orcinus orca], and polar bears [Ursus maritimus].

No, a narwhal isn't an invertebrate. Instead, it has a backbone. It belongs to the Chordate phylum, which has mostly vertebrate members. It also belongs to the class of Mammals, which all have backbones.

Like most marine animals, Narwhals possess a remarkably large layer of blubber wshich insulates them against the cold. They have a very thick layer of blubber.

Probably the most noticeable, most striking feature of the narwhal is its tusk. The feature is characteristic of males, very rarely of females. It consists of a 2-3 meter/7-10 foot long tooth that grows out of the incisor on the left side of the upper jaw.

No, narwhals aren't people eaters. In fact, they're picky eaters. Unlike sharks, they tend not to bite first and ask questions afterwards. They're committed to a set diet of specific Arctic fishes. They build their meals around arctic and polar cod, Gonatus squid, Greenland halibut, and shrimp. But they accept such substitutes as capelin and wolffish.

Yes they are. Remember that Narwhals are whales, and that whales are most certainly mammals.

The main narwhal body parts are a head and a streamlined body. The head includes a sharp, long, frontwards projecting, curved tusk that grows through the upper lip. It actually is a tooth that grows outward from the left incisor of the upper jaw. Narwhal bodies include short, broad pectoral fins and tails.

No, I don't have a pet narwhal [Monodon monoceros] named Fred. Nor is it likely that anyone else has a pet narwhal named Fred. Narwhals live in Arctic waters off the northern Canadian, Greenland and Russian coasts; and in the northern Atlantic waters off the Canada and Greenland coasts. So it's prohibitively expensive for a pet store to collect, transport, and maintain the large sized narwhals. Additionally, the record of narwhal survival in environments other than their native habitat isn't encouraging to any narwhal pet store operator or narwhal pet owner. The narwhal is a picky eater and fussy habitat dweller. It favors a specialized diet of Arctic and polar fare, and a specialized environment of Arctic and polar cold waters and ice.

Narwhals drink water when they feed. They suck in their prey, to be swallowed whole for digesting further down their digestive systems. When they do so, they let in a certain amount of water. Additionally, they meet their water needs through the moisture content of their aquatic prey.

The narwhal is a mammal. It's related to walruses, porpoises, and dolphins. Its specific, scientific classification is the following: Kingdom Animalia; Phylum Chordata; Class Mammalia; Order Cetacea; Suborder Odontoceti; Family Monodontidae; Genus Monodon; and Species Monoceros. Its particular scientific name is Monodon Monoceros, which is Greek for 'one tooth one horn'.

Narwhals follow a specialized diet that's available to them within the narrowly defined geographic region of the Canadian to the Greenlander to the Russian Arctic. Within that region, they favor Arctic and polar cod, Gonatus squid, Greenland halibut, and shrimp. But they also accept wolffish, skate eggs, and capelin. They do not, however, eat goldfish.
