Frogs have a green back that is smooth, soft and patterned, and a white belly. It can hide in the grass, so it is easier to catch pests and protect itself.

The frog's body can be divided into three parts: head, trunk and limbs. Frogs have four toes on their front feet, five toes on their back feet, and webbing. On the sides of the frog's head there are two small, slightly bulging bags, which are the eardrums, through which the frog can hear sounds. The skin helps to breathe. Only male frogs have air sacs. Frogs hunt with their tongues, which are covered with mucus.

Extended Information

The population of wild frogs in China is declining due to the multiple effects of natural and man-made factors. The high yield of frogs has attracted farmers to invest in frog farming, and with the aim of maintaining ecological balance, artificial breeding of frogs has been supported and encouraged. Due to the fact that China's current research on the breeding technology of frogs, the black-spotted frog, is not deep and the breeding technology is not yet mature, which makes the breeding success rate of frogs is not high.

Through investigation and research, it is found that the main reasons for the low survival rate of frog breeding are:

1, hostile

The frog itself lacks self-protection and external defense ability. Usually they passively avoid or protect themselves from external enemies through protective colors. Due to physiological and environmental changes, the young frogs that have just come ashore have poor environmental adaptability and fragile vitality. Exposure to sunlight and wind and rain in a dry environment is a fatal blow to frogs, resulting in a low survival rate of frog breeding.

2. Diseases

During the breeding process, due to the environment, climate and improper breeding, the seedlings and young frogs suffer from hemorrhagic disease, blistering disease, ascites disease, rotting skin disease, crooked head disease and so on, which directly affects the probability of the survival of the frog breeding.

3, bait

Frogs only eat live food. Under field conditions, flying insects are usually captured. The food for young frogs mainly includes mosquitoes, small insects, insect larvae and so on. Commonly frogs eat flies, mosquitoes, locusts, mole crickets, green worms, earthworms other insects. Artificial breeding is mainly feed-based, which is not conducive to the digestion of young frogs, affecting the survival rate of young frogs.
