I. The eggs are laid at different times

The toads lay their eggs in early April;

The frogs lay their eggs from late April to early May.

The shape of the eggs is different

The toad's eggs are "banded", like a continuous linear band, and the eggs in the band are arranged in two rows, like a string of beads, transparent with black particles.

The frog's eggs are "green globular," with larger grains, and the tadpoles that hatch are larger than those of the forest frog. The small toad's eggs are similar to those of the frog, but although they are also globular in shape, they are formed from several or dozens of eggs in a "small pile" of egg masses, and the tadpoles that hatch are yellow and have short tails.

Expanded Information

Frogs ovulate 3,000-6,000 eggs.

The males form mates by chirping to attract the opposite sex. After pairing, the female frogs begin to ovulate into the water, ovulating 3,000-6,000 eggs at a time; at the same time, the male frogs discharge sperm into the water. At the same time, the male frog discharges sperm into the water. The sperm and egg cells combine in the water to form a fertilized egg, which develops into a tadpole after 4-5 days of incubation.

The tadpoles must live in the water, swim with their tails, breathe through their gills, and eat plant foods such as diatoms and green algae. After two months of development, the tadpoles metamorphose into young frogs, with their tails gradually disappearing, their body lengths shortening considerably, and they begin to live on land, and their diet begins to change to one that is dominated by animal food.
