In the animal world broadcast on TV and movies, we can always see the scenes of fierce competition between male animals. Whether it is fierce tigers and wolves, docile herbivores, or even normally polite seagulls and winged butterflies, these male animals will turn into militants and fight against other males during courtship.
The struggle between male animals is undoubtedly a big competition of strength and endurance. For example, two bison can fight countless times until sunset, and some individual battles can even last for two days. The ventral side of all males turns red when the awnback silkfish is in estrus. For males, all other males are enemies. Even if the female is not around, the male attacks when he sees a red object. Scientists have also confirmed through experiments that male awnback silk fish are inherently aggressive during the breeding period.
Interestingly, although the struggle between male animals is fierce, in most cases, the winner stays, the loser retreats, and is very trustworthy. For example, the Micah cricket among insects, the winner has the wind of a gentleman, while the loser will be convinced and willing to bow to the downwind, and will never be entangled and beaten; Walrus, lions and other males, no matter how fierce the fight is, after one side concedes defeat, the other side will never kill them all. In the view of animals, the opponent's escape is to give up his rights and there is no need to pursue and kill again. However, there are exceptions. A few species of male fight also lose their lives. For example, male forest musk deer often cause great casualties because the fight is too fierce.
The struggle between the two males of most animals is the survival competition between the same species. They fight for the opposite sex, territory and status. In order to breed, males do everything they can to win the favor of females not only by fighting for territory with rich food sources, but also directly through wrestling. In a sense, fighting for territory means fighting for the right to mate with females. When males cannot participate in child rearing, the only benefit females get from sexual reproduction is that they can use the male's high-quality genes. Therefore, when choosing a mate, females tend to choose those males with high-quality genes, which are often expressed in the males who win the fight. In this sense, the love of fighting between male animals is not more a show off like humans, but a sacred and necessary way to reproduce better offspring.
