The skin can also help it breathe. Only male frogs have air sacs. The back is green, smooth, soft, and has patterns. The abdomen is white. It can hide in the grass, making it easier to catch pests and protecting itself.

Its skin can also help it breathe and has air sacs, which only male frogs have. It is very smooth, soft, and has patterns, and its belly is white.

The green back allows it to hide in the grass, making it easier to catch pests and also protecting itself.

When the weather turns cold in late autumn, frogs hibernate at the bottom of the water or in caves, and then return to the water to reproduce when the weather warms up in the spring of the following year.

Because their skin is exposed, they cannot effectively prevent the evaporation of body water, so they cannot live without water or a humid environment throughout their lives, and are afraid of drought and cold. Therefore, most of them live in tropical and temperate rainy areas, and very few species are distributed in cold zones.

Similar to frogs is the bullfrog, also a member of the family Ranidae. It is nutritious, delicious, grows fast, and has a strong ability to adapt to the environment. It has been introduced and bred in most countries in the world.

The whole body is a treasure, and it is a large economic frog that is used for food, medicine and skin. Bullfrog meat is a superior delicacy and a high-end health food. It is a healthy food with high protein, low fat and low cholesterol.

Bullfrog skin is a high-quality musical instrument material, a top-grade leather raw material, and can also be used to extract high-grade glue; bullfrog oil can be used to make high-quality oils and fats, and is also a good experimental animal and a loyal plant defender. Artificially cultivated bullfrogs grow fast, have high yields, low costs, high value, and have high economic benefits.

But now the audience is more concerned about the toad's eggs, which are long and there are a lot of them. A line of them looks like pearls when illuminated by the sunlight in the water. They also say that the toad's eggs are very tough and will not be deformed no matter how hard you pull them.

Some viewers in the live broadcast room talked about interesting things from their childhood.

"To be honest, I did this when I was a kid. I would pick up a handful of tadpoles from a small ditch or fish pond and bring them home. I would wait patiently for them to grow up, hoping that they would grow into cute little frogs."

"I was very excited at that time, looking forward to the little frog hatching every day, but I didn't expect that it would turn into a toad later."

Just by listening to the comments, many netizens felt the same way and felt devastated.

"I feel a little sorry for you. I know that feeling."

"So Brother Su, why don't you quickly explain this to everyone?"

The audience all said this, and Su Ran immediately said, "Well, I should remind everyone that whether it is a frog or a toad tadpole, it is best to let them grow in a natural environment and not just take them home to raise."

"As for how to distinguish frogs from toads, it's pretty simple to tell them apart based on the shape of their eggs."

"Different groups usually lay different eggs, which is related to their living environment and historical evolution. Generally, frog eggs are in the form of individual particles, with many eggs clustered together. Tree frogs usually lay foam eggs, which look like a balloon from a distance."

"While the eggs of toads are arranged in long tubular gelatinous egg bands in a unique chain-bead shape, the eggs of horned toads are mostly laid on the bottom of stream rocks in the shape of rings or blocks."

"If you miss the egg development stage and see them as tadpoles, you need to make judgments based on experience."

"The common toads around us include the Chinese toad and the black-rimmed toad. Their tadpoles are usually black, and these toad tadpoles like to gather together. If you see a group of black tadpoles gathering together in the pond, they are most likely toad tadpoles.

And speaking of which, the frog has a very interesting name, called field frog.

This name was originally a dialect in East China, and was later transliterated into Mandarin by randomly finding two homophonic characters. The "田鸡" in the dialect does not specify the two characters "田" and "鸡". It can be said that it is only the sound of oral communication but not the written characters.

So it has nothing to do with the "chicken" we talk about in daily life. At the same time, it is also because their living environment and some characteristics are similar to those of chickens. Because frogs often live in rice fields, feed on insects, grass, etc., and the taste of their meat is very similar to that of chicken, so they are called frogs.

However, compared to popularizing science about frogs, Su Ran is more concerned about letting the audience get to know toads better.

As a poisonous amphibian, the toxins it secretes are a means of protecting itself.

There are large bumps on the surface of toads' bodies. These bumps are their sebaceous glands, which can produce toxic liquids.

There are many sebaceous glands distributed on the body surface, most of which are not very large. The largest one is their parotid gland, which is very obvious and secretes the most toxins. When toads encounter threats from natural enemies, they will spray toxins.

However, generally speaking, they will not spray toxins easily. They will only spray toxins in emergency situations where their lives are threatened.

People also need to be careful when encountering toads, because toads may also spray venom on humans.

If humans do not actively approach to toads, they will generally be fine if they do not feel threatened. However, if humans approach them or try to catch them, they will think that humans are a threat to their lives and will spray venom to protect themselves.

The toad's venom is also harmful to humans, so you need to be careful.

Fortunately, humans are not the main natural enemies of toads.

Generally speaking, they are not particularly hostile to humans.

If humans do not actively provoke them, they will not take the initiative to bite or attack humans. However, self-defense is the instinct of all animals. When certain behaviors of humans threaten the survival of toads, toads will also protect themselves and may bite people.

So being bitten by a toad is definitely not worth it.

"But I remember that toads are quite valuable. In the past, during the spawning season in my hometown, toads would gather at the riverside or shallow water areas of the reservoir to start laying eggs."

"At this time of year, they come in pairs, either floating on the surface or lying on the river bank. Some villagers take advantage of the spawning period to catch them."

"I heard from others that you can sell toads for money. At that time, many people came together to catch toads when they lay eggs. You can catch more than 100 kilograms in one night."

"I did this when I was a kid. I would use a net to scoop up the toads when the water wasn't deep. But I didn't know they were protected animals. I thought toads were useless, so I just caught them."

Seeing the comments saying this, Su Ran was quite worried about them.

Although many people know that hunting toads, frogs, etc. is wrong, they do not realize that this behavior is against the law.

Although the toad is not included in the national wildlife protection list, it is included in the list of "three protected animals".

So, if you really catch a lot, it is not impossible to pedal a sewing machine. (End of this chapter)
