The number of wild frogs is the most from spring (February-March) to summer (May-August). Go into hibernation in autumn (end in October and slowly decrease)

How do frogs reproduce

Frogs are hermaphroditic, fertilized in vitro, and sperm and eggs are fertilized in water, so the pair of female and male frogs is beneficial for female frogs and male frogs to ovulate and ovulate at the same time, which improves the chance of sperm-egg combination and the fertilization rate.

The female frog lays the egg in the water, the male frog sprinkles the semen around the egg mass, carries on the in vitro fertilization, the fertilized egg carries on the self-incubation in the water, becomes the dark tadpole and then gradually develops into a frog.

Frogs belong to the amphibians of Chordata phylum, amphibia, Anura, Frog family. Adults have no tail, eggs are laid in water, fertilized in vitro, hatched into tadpoles, breathe with Gill, after variation, adults mainly breathe with lungs, and breathe with skin. The upper jaw has teeth, usually ploughbone teeth. Shoulder strap fixed chest type, vertebral body stagger type, sacral transverse process columnar; there is no interstitial cartilage between the two bone nodes at the end of the finger. The tympanic membrane is obviously hidden under the skin, the skin is smooth or verrucous. The tongue is generally long oval, and the back end is mostly notched.
