Introduction to frog:

Frog eggs are born in water, fertilized in vitro, hatched into tadpoles and breathed through gills. After the mutation, adults mainly breathe through the lungs and skin. Most frogs reproduce by in vitro fertilization, and fertilized eggs hatch outside the mother's body into tadpoles.

Frogs in the north are commonly known as Daqingguaizi, formerly known as frog, green chicken, sitting fish and salmon, and scientifically known as Rana nigromaculata, which is a national protected wild animal.
