Frogs are omnivorous animals, among which plant food only accounts for about 7% of the diet; Animal food accounts for about 93% of the diet. From the dissected 60 frogs, it was found that among the animal food, the animals that were swallowed involved 4 phyla, 4 classes, 10 orders and more than 30 families. 156 Among the preyed animals, Insecta accounts for 80%, and Lepidoptera is the largest: rice leaf roller 1 1, rice borer 10, rice corn borer 7, armyworm 10, corn borer 2, cotton bollworm 2 and pink borer 2. COLEOPTERA followed closely: 5 rice mud worms, 6 rice weevils, 2 scarabs and 4 ladybugs. Followed by Hemiptera (8 white-backed planthoppers, 7 gray-backed planthoppers, 2 rice black stinkbug and 6 brown-backed planthoppers) and Diptera (8 rice miners, 5 chironomids, 2 fruit flies and 3 mosquitoes). Anurak is an amphibian. Adults are basically tailless. Eggs are usually produced in water, hatch into tadpoles and breathe through gills. After metamorphosis, adults mainly breathe through the lungs, but most skin also has some breathing function. It mainly includes two kinds of animals: frogs and toads. ?

Frogs love to eat small insects and are good at finding moving small insects. When catching insects, their movements are as follows: a frog crouches in a small pit, with its hind legs curled up and kneeling on the ground, supported by its front legs, with its mouth open, its face up and its stomach bulging, waiting for something. A mosquito flew over and dangled in front of the frog. The frog jumped up with a jerk, turned his tongue and fell to the ground again. The mosquito disappeared, and it sat motionless, waiting for the arrival of the next prey.

There is a bulging thing on the frog's mouth that can make a sound. It likes to sing loudly on rainy days in summer. In hot summer, frogs usually hide in the grass and occasionally make short calls. If there is a cry, the people next to them will scream a few times, as if singing to each other. Frogs are happiest after the heavy rain. At this time, there will be dozens or even hundreds of frogs croaking endlessly, and the sound can be heard for miles away. ?

Vocal cords are the vocal organs of frogs. Located above hilar cartilage. On both sides of some male frogs' squabble, there are external sound sacs that can expand and vibrate, and the sound sacs resonate, making the frogs' songs magnificent and loud. Strolling to the pond, you will hear the cries of male frogs echoing each other, one after another, and merging into a chorus. Scientists point out that frog chorus is a veritable chorus, which has certain rules, including lead singer, chorus, chorus and accompaniment, and is closely coordinated with each other. It is speculated that chorus is much better than solo because it contains more information. Chorus is loud and far away, which can attract more female frogs, so frogs often adopt chorus form.
