Why can't you eat frogs?

Frogs mainly feed on agricultural pests. Through observation, we know that as soon as the flying borers, jumping locusts, rice budworms hiding in leaf rolls, cotton bollworms burrowing into cotton bolls, and mole crickets hiding in underground caves come out to move, frogs will immediately catch them. The agricultural pests preyed by frogs are of many types and in large numbers. According to statistics, a frog eats about 60 pests a day. In the 6 or 7 months from spring to autumn, a frog can kill more than 10,000 pests, which is a considerable number.

What is the difference between a bullfrog and a frog?

1. Frog

1. They are found in almost all regions of the world except Australia, the driest deserts, and many overseas regions. However, most species of frogs are concentrated in the warm and humid tropics.

2. Frogs have smooth, moist skin, protruding eyes, and exposed eardrums behind their eyes. Adult frogs have no tails, but their hind legs are long and strong, and they can jump very far. Many species of frogs have webbed feet, and are natural swimmers.

3. Frogs are experts at catching pests in the countryside and are protected by the state as beneficial animals to humans. A frog can catch 1,250 insects per month and kill more than 10,000 pests per year.

4. Frogs are southern species, and their domestication technology is not yet mature, so they cannot be eaten.

2. Bullfrog

1. A type of frog native to the western Rocky Mountains of North America. It is a large edible frog second only to the African woodland frog.

2. The female frog is up to 20 cm long, while the male frog is 18 cm long. The head is wide and flat. The mouth is terminal, with a pointed round tip and a blunt surface. The eyeball is protruding and divided into two parts, with a foldable nictitating membrane on the lower eyelid to close the eye. The back is slightly rough with fine skin ridges. The limbs are stout, with short forelimbs and no webbing. There is an obvious gray tumor-like protrusion on the inner side of the first toe of male individuals. The hind limbs are longer and larger, with webbing between the toes. The skin color varies with the living environment. The back and limbs are usually green-brown with dark brown markings on the back; the head and mouth edge are bright green; the belly is white; the color below the throat varies with the sex, with females mostly white, gray or dark gray, and males golden yellow.

3. Because of its loud and clear call that sounds like a cow, it is called bullfrog. It also has the ability to prey on insects, but because of its large size and delicious meat, it is artificially raised as a delicacy and introduced into my country. Bullfrogs have a long lifespan, generally 16-20 years.

Are frogs warm-blooded or cold-blooded animals?

Frogs are cold-blooded animals, and their body temperature changes with the temperature of the outside environment. Frogs belong to the phylum Chordata, and are amphibians of the family Ranidae. They lay their eggs in water, and use in vitro fertilization to hatch into tadpoles. They live in rivers, ponds, and rice fields, and they mainly move around in the grass by the water, and sometimes lurk in the water.

Frogs are cold-blooded animals. The temperature of their bodies changes with the temperature of the environment. If they are under the sun, their bodies will become warmer, but if they are in water or in a cool place, their body temperature will gradually decrease. Therefore, frogs are not warm-blooded animals, but cold-blooded animals.

Frogs belong to the order Anura of the class Amphibia of the phylum Chordata, and are amphibians of the family Ranidae. Frogs do not have tails, and they lay their eggs in water, using in vitro fertilization. The eggs hatch into tadpoles, which breathe with gills, but after mutation, frogs breathe with lungs and also breathe with skin.

Frogs usually live in rivers, ponds, rice fields and other places. They move in the grass near the water and sometimes lurk in the water. Most frogs are active at night. Their main food is some insects, such as snails and snails, and most of the insects they eat are agricultural pests. Frogs are animals that are beneficial to agriculture.
