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 foods, 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. There is no strict difference between these two animals, and some families have both. Generally speaking, toads live on land, so their skin is rough; Frogs are slim and good at swimming. The two bodies are similar, with inconspicuous necks and no ribs. The ulna and radius of the forelimb healed, the tibia and fibula of the hind limb healed, the claws could not rotate flexibly, but the limbs were muscular.
Frogs like to eat small insects. When it catches insects, it moves: a frog crouches in a small pit, with its hind legs curled and kneeling on the ground, its front legs supported, 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 quietly, waiting for the arrival of the next insect. This frog has a white belly, a yellow-green head and back, and some dark brown stripes. Some have three white marks on their backs. Why are frogs green? It turns out that the frog's green clothes are a good disguise. It is almost the same color as the grass in the grass and can protect itself from the enemy.
