During the oviposition period, the back of the female toad ** softens like a sponge, the cloaca wall stretches out to form a tubular oviposition belt, bends up to the back, the male toad presses the oviposition belt on the back of the female toad, squeezes out the eggs, presses into the spongy ** nest, and covers it with gelatin. The eggs develop in the ** nest on the back of the female toad, and after the tadpole stage, they become young adults before leaving the female. Opossum toads have this"Opsi"habits.

The spawning season is between late February and March, and the egg colonies are stacked eggs with about 250 346 eggs per egg. above the base of the tadpole tail"y"The spots are narrow, the tail has a considerable number of dark markings, and the tail"y"The spots are more pronounced. It is distributed in Guizhou (Yinjiang, Jiangkou), Sichuan (Emeishan, Dujiangyan, Yunlian, Ya'an), Yunnan (Daguan), Chongqing (Youyang), Hunan (Sangzhi, Shimen), Guangxi (Tianlincen Wanglaoshan).

In winter, they dive underwater and hibernate in rotten grass or mud. It is not until the next year that the sting is stunned, and then the hibernation life is over, and the ground is crawled to the ground. The Chinese toad feeds mainly on insects, which is beneficial for agriculture and forestry. The white viscous fluid secreted by the glands behind the ears can be made into the precious Chinese medicine "Toad Crisp".
The above is the introduction of the five varieties of leprosy. Although their names may sound a little uncomfortable, they play an important role in the ecosystem. We should respect every living thing and protect our common home.
