The most massive creatures on earth today are blue whales wandering in the ocean. Their average weight is 180 tons, which is more than 360,000 catties. It can be achieved with just one tongue. The weight of 4,000 kg is really a big mouth. Such a large male blue whale, its testicles are not very heavy, only less than 90 catties, this ratio is more in line with the animal golden ratio. However, there is an animal that is very anti-scientific. Its size is not the largest, but the weight of its testicles is the highest in the world. It is the right whale that everyone does not know much about.
Right whale, which lives between the Atlantic and Pacific Oceans. Its body surface is very smooth and hairless. Its body size is only half the size of a blue whale. It is about 18 meters long and weighs only more than 100 tons, about 20 Ten thousand catties, the entire head occupies a quarter of the body. It can be said that he is a guy with a big head. The beards on both sides are 2.9 meters long. The female is much larger than the male. This is also a rare phenomenon in the animal kingdom. It is simply a manifestation of Yin and Yang. , The female right whale is still the queen of the entire population, in charge of all affairs in the entire population, all males must obey the females, this organizational discipline is very strict.
Female right whales, within their own territorial waters, other female right whales are not allowed to enter, and their males are also not allowed to mate with other females without authorization. It can be said that a huge size advantage In the entire sea area where female right whales are strictly controlled, almost everything is done by a mother whale. Once other female whales invade their own waters, the female right whale will order the male to expel the outsider and force it to leave its own territory. This is the Queen’s unique right, and no male is allowed to challenge its authority.
Because female right whales have such a queen-like authority, they practice polyandry ,In the entire sea area, only one female is allowed to exist, and all males are just its servants. But not all males have the right to mate with the queen. Female right whales are very demanding in the choice of mating partners, especially because they value the small size of the male testicles. Only the larger the male’s testicles, the more attractive it is. Winning the favor of the queen of female right whales, any male with a small testicle has no chance to mate with the queen, nor can he beat the queen with a huge body. Those male right whales only deserve to be a bachelor for a lifetime.
As the instinct of animal inheritance, in the process of evolution that has gone through hundreds of thousands of years, these male right whales are in the process of evolutionary evolution in order to obtain their own mating power and pass on their genes. In the middle of the world, they continue to please females. Since female right whales like males with large testicles very much, all males are constantly striving to make their testicles bigger in the process of evolution. This kind of almost abnormal evolution The procedure, which has continued to modern times, has become a strange and inexplicable phenomenon.
Today's male right whales, the average testicle weight has reached 1,000 kg, and some of the more massive and mighty male testicles have reached 1,500 kg, making it the largest animal on the planet with the largest body size. The testes of the male blue whales are also 20 times larger. The weight of this testicle occupies 1% to 1.5% of the weight of the entire body. We can make an analogy. According to the weight of the testes of a male right whale, an adult man weighing 150 pounds should weigh 1.5 to 2 pounds. If humans really have such a large testicle, it is definitely a macho. Characters, it's no wonder that female right whales like males with huge testicles so much.
The reason for the huge testes of male right whales is, in the final analysis, the vicious competition between males. Due to the strict control of polygamy in female right whales, if males want to obtain mating rights, they must constantly grow their testicles. In this process, it is a process of comparison and competition. Males with smaller testicles will Faced with the danger of being eliminated, even in the ethnic group, there is no status, there is no way to obtain the right to mate,Its genes will be recognized as garbage and gradually eliminated.
Every male right whale wants to continue its genes. Therefore, this vicious competition puts all the focus on growing the testicles. After hundreds of thousands of years of evolution, The ending today. It can be said that the huge testes of male right whales are the result of vicious competition under the polygamy practice of female right whales. (The picture comes from the Internet)
