What are the characteristics of a frog's habits?

The frog is an expert at eliminating pests, with a green back, a white belly, and two slightly bulging little sacs on either side of its head. So, what are the habits of frogs?

1. The frog is an amphibious animal, usually dwelling in the grass along rice paddies, ponds, ditches or riverbanks, and sometimes lurking in the water. When young it can only live in water, and after growing up it can live on land. When the weather turns cold in late autumn, it lies dormant at the bottom of the water or in a burrow to hibernate, and when the weather warms up again in the following spring, it returns to the water to breed.

2. The frog is an omnivorous animal, of which plant-based food accounts for only about 7% of its diet, while animal-based food accounts for about 93%. It is mostly active at night and feeds mainly on insects; the vast majority of the insects it eats are agricultural pests, and it also feeds on some river snails, snails, small shrimp, small fish and so on. Some people estimate that a frog can prey on 70 insects a day and can eliminate 15000 pests a year.

3. Frogs can sing. There is a bulging sac at the side of their mouth that can produce sound. They love most to sing loudly on rainy summer days, and they call most joyfully after a heavy rain. If one calls, the ones nearby will also call along, and at such times, dozens or even hundreds of frogs will croak “ribbit” endlessly.

4. Frogs can jump on the ground, and a single jump covers a distance as much as 20 times their body length; they can also swim in the water, with the most standard breaststroke posture; but their crawling movements are very sluggish. Their eyes are slow to see still things and keen to see moving things, so as long as a small flying insect flies past them, the frog can quickly stick out its long tongue and swallow the pest in one go.

5. Frogs are oviparous, generally laying eggs and fertilizing them in water; after the eggs hatch they become tadpoles, which are black, with round bodies and a long tail. The tadpoles grow day by day, first growing hind legs, then front legs, and the tail gradually shortens and degenerates, finally turning into a frog.
