There are four kinds of animals such as quail, frog, crab, and squid, and many people are difficult to identify male and female. In fact, after the maturity of these four animals, appearance characteristics can be used to judge males and females.
(a) 鳖: genus reptilia, 鳖. Alias ​​are turtles, fish, round fish and so on. The cubs are difficult to identify, but after sex matures, they can be distinguished: the female baboons have a thicker body, the back has an oval shape, and the middle is flat. The tail is short and does not naturally extend beyond the skirt. The male figure is thin, the back of the carapace is more elliptical than the front, and the middle part is uplifted. The tail is long and can naturally extend out of the skirt.
(b) Frogs: Amphibian animals. The main characteristic of the male frog is that the first base of the forefeet has a finger pad (ie, grand-like), and there is a pair of “acoustic sac†on both sides of the mouth. When the male frog is called, the sac bulges like a balloon and it starts to bulge. The Role of Loudspeakers During the mating season, male frogs rely on calls to lure female frogs.
(c) Crab: A crustacean and a decapod. There are many species, most of them live in seawater, and there are few species in fresh water. Identifying male and female mainly depends on the crab umbilical. Those crabs whose umbilical cords are round or elliptical are female crabs and males with triangular or sharp triangular shapes are male crabs.
(d) Astragalus: a bony fish skeleton and a cockroach family. The body has a dome shape, up to 50 cm long, yellow-brown, large head, large mouth, thick lips and small eyes. Living in mud ponds, ditches, and rice fields, the plants are widely distributed throughout the country. Astragalus has a "sex reversal of the special secondary students, which is unique in fish and extremely rare in the entire biological community. The cubs that hatch from the eggs are all female, and none of them are male. Females grow to a certain degree, the gonads mature, and they also breed through mating and spawning. After several generations of reproduction, the gonads in the body gradually change, and the female nymphs become males, that is, the original ovary. It evolved into a seminal vesicle that produced sperm, and this process of change called it a reversal of sex. It can be seen that in such a "sexual reversal, males always mate with the next generation of females. A group of females were born, a group of females laid eggs, and a group of females became males. This will allow the entire race to multiply. According to an anatomical observation by the scientists, when the length of females reaches 25 cm, they are mature and spawning. When the body is 35 centimeters in length, half of the bodies become males. When the body is more than 45 centimeters in length, all become males.
