Are frogs animals or beneficial insects?

Frogs belong to amphibians. Beneficial insects refer to insects that are beneficial to human production and life. Frogs do not belong to insects, so they cannot be considered beneficial insects. They can only be said to be a type of animal that is beneficial to humans.

Frogs belong to amphibians, because beneficial insects refer to insects that are beneficial to human production and life. Frogs belong to amphibians, not insects, so they cannot be considered beneficial insects. They can only be said to be a type of animal that is beneficial to humans.

Frogs are amphibians belonging to the phylum Chordata, class Amphibia, order Anura, and family Ranidae. Adult frogs have no tails. Their eggs are laid in water, fertilized outside the body, and hatch into tadpoles that breathe with gills. After mutation, adults breathe mainly with lungs and also through their skin.

Frogs often live in rivers, ponds, and rice fields. They mainly move in the grass near the water, and sometimes hide in the water. They are mostly active at night, and feed mainly on insects, as well as some snails, snails, shrimps, and small fish. Most of the insects they eat are agricultural pests.

Why do frogs appear when it rains?

Reason 1: After the rain, the air becomes moist and frogs become active.

Reason 2: After the rain, the amount of oxygen in the water decreases, while the amount of oxygen in the air increases, so frogs will come out of the ground to breathe fresh air. Reason 3: It is determined by the frogs’ habits. Frogs often reproduce after the rain.

Frog species

Frogs are amphibians of the family Ranidae, with more than 6,000 species in the world. Among them, the most widely distributed and abundant ones include the black-spotted frog, the marsh frog, the golden money frog, the tiger-striped frog, the small spiny frog, the bullfrog, the red-webbed tree frog, the black-webbed tree frog, the Coro Australian toad, the piano frog, and the red-backed poison dart frog.

There are more than 6,000 species of frogs in the world, and there are about 190 species of frogs in China.

Frogs have poor thermoregulation ability and are cold-blooded animals whose body temperature changes with the external environment. Generally, the body temperature of frogs can vary between 3-36 degrees.

Frogs can be bred artificially, and the ones commonly bred are black-spotted frogs and tiger frogs.

The largest frog in the world

The largest frog in the world is the African giant frog. It is the largest frog in the world and can be called the "giant" among frogs. The length from mouth to buttocks reaches 33 cm, and the diameter of the eyes can reach 2.5 cm, which can be called the "big eyes" among frogs.

The mouth is wide and can swallow relatively large food. There are small teeth on the upper jaw to prevent food from slipping out of the mouth.

The skin on the back is granular and warty, with a greenish-brown color, and the adult frogs are well camouflaged when basking on wet moss-covered rocks.

The root of its tongue grows in the front part of the lower jaw, while the tip of the tongue is facing inside the mouth. The tongue can be turned out of the mouth and stretched out very long, thus expanding its feeding range.
