There is a green frog squatting on the toilet at home, is it auspicious

Frogs belong to the amphibians of the phylum Chordates, amphibians, anceridae, and frogs, adults without tails, eggs are laid in water, fertilized in vitro, hatched into tadpoles, respire with gills, and after mutation, adults mainly breathe with lungs and skin. The vast majority of frogs reproduce through in vitro fertilization, and the fertilized eggs hatch into tadpoles outside the mother's body. Globally, only 10 to 12 species of frogs have evolved to fertilize in vivo, and some of them will release fertilized eggs from their bodies to hatch into tadpoles.

But frogs are zoological to refer specifically to the black spotted lateral fold frog. Frogs have long been thought to be oviparous, but scientists have found that a species of frog that lives in the rainforests of Sulawesi, Indonesia, is capable of laying tadpoles. This frog is the only one of more than 6,000 species of frogs in the world that can"Lower tadpoles"of frogs.

Frogs are slimmer and are more good swimmers. The neck is inconspicuous and has no ribs. The ulna of the forelimbs heals with the radius, and the tibia of the hind limbs heals with the fibula, so the claws cannot rotate flexibly, but the limbs are muscular.

The most primitive frogs began to evolve in the early Triassic. The first frogs to jump appeared in the Jurassic period. Because frogs feed on insects and other invertebrates, they must live near water.

There are about 130 species of frogs in China, and almost all of them are experts at eradicating pests in forests and farmlands.
