Frog (Latin name: Rana nigromaculata, alias: toad), a frog [1], is a national third-class protected animal. It often inhabits rivers, ponds and rice fields, mainly moves in the grass near the water, and sometimes hides in the water. Frogs have a flat head and a slightly pointed nose and mouth; The mouth is very wide and consists of upper and lower jaws; Eyes are big and prominent, born on the left and right sides of the head. The trunk is short and wide, and there is a small hole between the legs at the back end of the trunk, which is a cloacal hole. The forelimb is short and consists of five parts: upper arm, forearm, wrist, palm and fingers. The hind limbs are long, the toes are developed and webbed. Its eggs are laid in water, hatch into tadpoles and breathe through gills. The reproductive characteristics of frogs are hermaphroditism, fertilization in water and oviposition.

The common frogs in farmland are Rana nigromaculata, Rana zewalskii, Rana aurea, Bufo raddei, etc. The bullfrog introduced from Cuba can be regarded as a "giant" among frogs, and its body length can reach 20 cm. Its Cleisthenes songs are very similar to those of Niu Jiao, so they are called bullfrogs. There are about a dozen tree frogs in China. They are light and thin, with suction cups at their fingertips. They are good at climbing tall trunks or bushes, and their body color is consistent with their surroundings. The smallest frog in the world is Nepenthicola, which was discovered by scientists in and around Nepenthicola in the rainforest of Borneo Island, Malaysia. This newly discovered adult male frog is only about the size of a pea. This size makes them difficult to find. Fortunately for scientists, however, this frog loves to bark very much and makes a loud noise.
