The horns of narwhals are worth as much as gold, and the horns are used for hunting? Why are there no narwhals in the aquarium?
This is a narwhal, at this time it is facing a group of Inuit roundup, only a while, it was caught ashore by the Inuit to decompose the body, the biggest feature of narwhal is its long horns on the head, generally speaking, adult narwhals' horns can reach more than two meters long, its horns are very precious in the human world, and the price of gold has a batch, and some people do not hesitate to take out the castle to exchange. Although precious, it is of little use to the Inuit, who prefer narwhal meat, knowing that the Inuit are the only people in the world that can legally hunt whales, and the whales they catch can only be eaten by themselves, and cannot be profited from. Inuit live near the unusually cold Arctic Circle, and because of the lack of food, they often go to the sea to catch fish for food, and catch two or three whales a year. Not only did the Inuit like it, but medieval Europeans loved it wildly, and under the packaging of merchants, they sold narwhal horns as unicorn horns until the 17th century. However, people are still curious about this mysterious species, because it is the only species of all cetaceans that grows horns, which is very fierce.
Everyone is curious about what the long horns on the narwhal's head are used for? Is it a great weapon for hunting or fighting? To be precise, it is not its horns, but its teeth, which are not born without this tooth, which slowly grow in later development, and as long as it does not die, its horns will continue to grow. Its horns are very slender, many people imagine that it uses its tusks to aim at its prey and rush over, sneaking its prey onto its tusks, although it feels interesting, but if narwhal is this way of hunting, they are likely to not eat, after all, there is no hand to remove food. In 2017, researchers used drones to capture a group of narwhal predators, they surrounded cod, slowly narrowed the encirclement, aimed at a cod, and then swung the long teeth on their heads to stun it. Since it can be used to catch fish, can it be used to fight? In 2014, scientists witnessed 20 killer whales hunting more than a dozen narwhals, and as a result, all narwhals were killed, and the reason why they did not use tusks for defense was because their tusks had no enamel, which means that the teeth were sensitive and fragile, and could be used to hunt small fish at most.
There are many fish in the aquarium, fierce sharks, mischievous beluga whales, trick-or-treating killer whales, etc., why are there no narwhals? In history, there have been people who have kept narwhals in captivity, which happened in 1968 in the Vancouver Aquarium in Canada, before the aquarium already had dolphins, beluga whales and killer whales and other marine animals, most of these animals are found in aquariums, in order to make a gimmick, the director of the Vancouver Aquarium proposed to introduce narwhals. In August 1970, a young male narwhal was captured on Elsmi Island, followed by two adult males and three young whales. Unfortunately, the three young whales died after three weeks in the aquarium, and two male narwhal died two months later, the mayor of Vancouver asked to release the last narwhal, the aquarium curator was unwilling, and then the last male narwhal died a month later, and no aquarium has ever kept narwhals in captivity. For the reason why narwhals cannot be kept in captivity, it is said that narwhals need a lot of space to move, which aquariums cannot satisfy, and slowly cut off the idea of captive narwhals. Do you think this statement is correct?
