I used to hear people say, "This man is easy to bully, like a crab." I have always had a question: "Why do crabs bully people?" I asked my mother, and she said, "Because crabs walk sideways." So, I want to buy some crabs to observe. Today, dad bought crabs to observe.

The crab * * * has eight feet, and two big pliers like scissors. It's terrible to stare at you outside. Through observation, I found that several crabs have extremely large pliers covered with thick black hair. The pliers of other crabs are smaller, and there is not much black hair on them. I also found that the covers on the stomachs of some crabs are sharp, like towers, and some are oval.

I asked my father what was going on, and my father said, "Did you find out? The pliers of the pointed cover are big, and the pliers of the round cover are small. " I looked at it again and found that it was really like this. Dad added: "The pliers with pointed cover are male, and the pliers with round cover are female.". The male has to protect his family, so the pliers are big. "

At this time, we untied the crab's rope and saw the crab climb up quickly with its eight thin and long legs. I found it crawling sideways like my mother said. Today, I finally solved the problem of why crabs bully people.

Through this experience, I know that I should observe and think more in my life, so that I can increase my knowledge.

Observing small animals composition II

Yesterday, my father caught a lovely little snail for me. I found a small cup to make a snail's home. At first, the little snail was shy and shrank his head into the hard shell. Slowly, he became familiar with this strange little home. He stuck his head out and shook his two tentacles as if he were greeting me.

After a while, the little snail wants to climb out to find food. I was worried that it would crawl away, so I took a small piece of paper, put it on a small cup, and pierced a small hole so that the little snail could not climb out to breathe fresh air.

The next day, something unexpected happened. The little snail bit a big hole in a small piece of paper and ran away. I am in a hurry, but I can't find the snail anywhere. I asked my mother, "isn't this small home very nice?" Why did the snail run away? " Mother said, "Little snail likes nature, green grass and beautiful flowers.

On the third day, I finally found the little snail! The little snail is dying, and I don't know if it can live. I put snails by the pool and some apple skins. The little snail actually began to eat the apple skin!

The vitality of the little snail is really strong!
