We often mention "unicorns" in our lives, such as some high-end technology companies in the stock market, and then the fictional white horse in Western mythology, and so on. In reality, there is really a long and pointed unicorn beast, which is a "narwhal".

As the name suggests, this is a mammal, a whale that lives in the ocean, not a fish. It is said that in the 16th century, the Queen of England once bought a horn of a narwhal for the price of a castle. Speaking of which, do you also want to sell the whole one? No, we have to love small animals.
However, the body of the narwhal can be about 5 meters long, and its horn can grow to 3 meters long, which is not a small animal. Personally, I think it looks a bit like a fencer! Yes, the "sword" on its head is really a weapon, and it is the male narwhal who competes for the leadership of the team, the leader of the group, and the weapon that the female favors. Female narwhals generally do not have "horns", or the "horns" are short.

Well, let me reveal a little more secret. The so-called "horn" of the narwhal is not actually the "horn" on the top of the head, but the canine teeth that grow out of its mouth. Usually a male will focus on developing a canine tooth, which is the common "one horn", but occasionally a male will grow 2 long canine teeth!

So don't you wonder how the teeth of this cargo can be so long, so straight, so pointed? If you are interested, please leave me a message Ha, I will reply one by one.
