Read below to complete the questions. In the eyes of many people, snails are weak small animals, they are slow, vulnerable, encounter natural predators, almost can only sit and wait, but another indisputable fact is that snails are one of the most widely distributed and most numerous animals in the world, they are found all over the world, forests, meadows, ponds, swamps, mountains, flats, hills and other places can be seen everywhere, and even in some alpine areas can be found their clumsy but determined figure. The fact that a population can thrive must be related to its strong adaptability.
In fact, when it comes to adapting to the environment, the snail is an out-and-out powerhouse. The snail's foot has a special structure called a trap.
It's the equivalent of a snail's shell. Once the snail has a premonition of danger, it will retract its body into the snail shell and seal the mouth of the snail shell with a trap to create a closed space. It will not come out again until it senses that the alarm has been lifted.
So how long can a snail stay in its shell at a time? Hours, days, months, or even years are possible. The snail hiding in the shell can reduce its metabolic rate to a very low level, and can only maintain the most basic life activities such as respiration and circulation.

Scientists finally unravel the mystery, there is a bird called dark green embroidered eyes especially like to eat tiny flea snails, but a small part of the snails after being swallowed by the birds, can tolerate the bird's digestive juices, and finally escape with the feces excreted by the birds, Japanese researcher Yuya Ichiro said: "We found that about 15% of the small snails are still alive after being digested by the birds."
Terrestrial invertebrates without wings that are geographically restricted.
In particular, why are snails able to migrate to great distances? Perhaps the mystery can be solved by explaining them with the help of birds' feet, intestines, or tornadoes.
is spread out over a wider area. "The digestive juices of animals are extremely corrosive and can melt steel, and some seemingly weak snails can survive in them, and with the help of "bird wings", they have successfully expanded their "sphere of influence", which cannot but be said to be an ingenious survival strategy. In our consciousness, fast, aggressive, and ferocious are the symbols of the strong, but the logic of nature does not seem to be so, otherwise, how can slow, weak, and small snails also be in the law of the jungle of "survival of the fittest".
The next life is endless? (1) Snail "cow" in **? (2) Read the following sentences carefully, and analyze and explain the characteristics of the language in combination with the dotted words in the sentence.

The author compares snails with the strong to show that not all strong people can win in nature.
Thank you. What about the world's weaker animals that are also widely distributed and numerous? What are the revelations, related to the reality of life, how to write.
There are also ants, earthworms, mosquitoes, flies, these are small animals, but they are widely distributed.
The revelation is that although they are weak, they also have their own way of survival, and they are strong in breeding, they do not need much food, and they can adapt to the changes in the environment.
Therefore, if you want to survive, you must learn to adapt to the environment, learn to make trade-offs, and don't be greedy for too much, because greed will become a burden on life.

What is the color of a snail's shell used for?
Protective colors, like the color of earth, to hide from the attention of predators.

How does a snail react when you touch its antennae with a glass rod?
The antennae will immediately retract, even into the inside of the head. The antennae are like the blind cane of a blind man, and the snail only has a sense of light but no vision, so it relies on it to find its way when it walks.
Use the glass rod to touch the snail's abundance, torso, and shell. Which part of it is the most sensitive?
Of these three places, it is abundance that is the most sensitive. For the whole body of a snail, it is the antennae that are the most sensitive.
Place the snail in the shade and shine a flashlight at it from the front, and its reaction is to retract its antennae, then slowly extend it again.
Dip a cotton swab in a small amount of vinegar, close to the snail's head, and it reacts:
The tentacles suddenly retracted, and before the tentacles could be extended again, they turned their heads and "ran".
Half a meter away from the snail to clap its hands, the snail's reaction is: there is a vibration and the air flow is felt by the antennae, and the antennae will shrink a little.
