Frogs belong to chordates, amphibians, Anura and Ranidae. Adults are tailless, eggs are laid in water, fertilized in vitro, hatched into tadpoles, and breathed through gills. After the mutation, adults mainly breathe through the lungs and skin.
Frog is a protected animal prohibited by the state, but in daily life, many people regard frog meat as a tonic or delicious food, which leads some vendors to kill frogs on a large scale. Catching frogs will inevitably destroy the ecological balance and lead to the proliferation of pests.
In order to ensure the yield of crops, people must use a lot of pesticides. Pesticides accumulate in frogs after they eat some lucky pests. People who eat too much frog meat are prone to food poisoning. This will be harmful to human health.
