Narwhals belong to the animal kingdom, Chordata, Vertebrate, Mammalia, Cetacea, Toothed Cetaceae, Narwhal Subdivision and Narwhals. Hehe, I don't know if it's nonsense. Latin scientific name Monodon monoceros English name Narwhal.
If you ask narwhals if they sleep, you can tell them that they do. Because mammals need to breathe with their lungs, whales should expose their breathing holes to the sea when they sleep. The narwhal's longest sleep time is only 10 minute.
In terms of food, narwhal's food includes many kinds, including fish, marine mollusks and other small creatures. When foraging, it will be carried out in small groups.
Narwhal is a cetacean that lives in the northernmost part, so it migrates every spring and autumn. For example, in autumn, it will migrate to an unfrozen ocean. Usually, narwhals live in small groups of about 20, and then they gather into loosely integrated large teams, sometimes hundreds of small teams will form thousands of large teams. At this time, the parade area of male adult narwhals, female whales and young whales will be different and closer to the deep sea. There is no big seasonal difference in other behaviors except migration.
Well, maybe that's all I know. I wonder if it will help you. But now that it's said, let's talk about their long horns. Some people who don't know can know a little about it.
The narwhal has two teeth in its upper jaw. At about one year old, the teeth on its left side will protrude. Finally, it will drill through its upper lip and grow into a unique "long horn". Generally, the long horn will be about 2 meters, and the longest can reach 3 meters. The base is 30 cm in circumference and weighs 10 kg. However, two thousandths of male whales have protruding teeth on both sides, forming a pair of long horns, but the protruding teeth on the right side are generally shorter and thinner than those on the left. 3% females also have prominent left tusks due to mutation, but they are much shorter than males, and the longest is no more than 1 m2. Female whales with protruding teeth on both sides are extremely rare, and only one case has been recorded so far.
The use of ivory has always been a mystery, with various speculations and many mythical explanations. Reasonable tools include harpoon, ice-breaking breathing hole, etc. In fact, it's like a deer's horn, which is a weapon for male whales to compete for mates. During the breeding season, males will fight to decide their reproductive rights. Generally speaking, the position of male whales in the whale population is also proportional to the length of their tusks.
Well, if you're interested. We can talk more.
