What did the frog find in the short article Fear?

Frogs are amphibians, belonging to Chordata, Amphibia, Anura and Ranidae. Its adult has no tail. Its 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. Most frogs reproduce by in vitro fertilization, and fertilized eggs hatch outside the mother's body into tadpoles. Only 10 to 12 frog species in the world have evolved into in vivo fertilization, and some of them will expel fertilized eggs and hatch into tadpoles. But in zoology, the frog refers to the black-spotted lateral fold frog.

Frogs are amphibians, usually inhabiting rice fields, ponds, ditches or riverside grasslands, and sometimes lurking in the water. When I was a child, I could only live in water. I can live on land when I grow up. Hibernate at the bottom of the water or in caves when the weather gets cold in late autumn, and then return to the water to breed when the weather gets warmer next spring.

Frogs lay eggs. They usually lay eggs and fertilize in water. After eggs hatch, they become tadpoles. Tadpoles are black, round and have a long tail. Tadpoles grow up day by day, first grow hind legs, then front legs, and their tails gradually shorten and degenerate, and finally become frogs.
