Do you know the story about why crabs always walk sideways?

From a biological point of view, the crab's chest is wider left and right than front and back, and its eight legs stretch on both sides of the body. Its front foot joints can only bend downward. These structural characteristics also enable the crab to only Walk sideways. Story 1 is like this:

It was a moonlit night.

The little crabs chattered on the beach.

The mother crab suddenly screamed in fright.

"Oh! Child! Why are you walking sideways? It's so ugly!

You will be laughed at by everyone! You must walk straight!"

< p>"I know! Mom!" However, I still don't understand.

With bubbles coming out of his mouth, he said:

"Well, mom, can you show me and demonstrate? I will do it!"

"Okay! It's very simple!"

Mother Crab tried to walk straight, but no matter how she walked, she could only walk sideways.

Mother Crab is so discouraged!

The little crab can only follow its mother's example one by one. Story 2: Crawling Crabs

A group of small animals such as white rabbits, turtles, frogs, crabs, ants, etc. stood together, ready to go out for fun. Their destination was the beautiful garden in front. The frog with a loud voice shouted: "Let's go!" Everyone took action immediately. The frog jumped and shouted "Come on!" The white rabbit rushed ahead with a smile, the turtle crawled hard, and the ants chased desperately...

"Hey, are you all crazy? Where are you running from behind?" There was a faint cry.

Everyone was startled and turned around to look back. They saw the crab yelling and crawling sideways in the other direction.

"Brother Crab, you are going in the wrong direction!" the frog shouted, "come closer to us!"

"Fuck you," the crab glared and cursed, "you all You are blind, so you can only move closer to me."

No matter how everyone called, the crab just pretended not to hear it and still crawled sideways in its direction. Everyone sighed and had to go their own ways.

The crab sprayed white foam and muttered alone: ??"I always stare directly at that garden, it's absolutely right. They don't listen to me, alienate me, and neglect me, it must be because of Jealousy. Hey, isn't it obvious? Which one of them has more arms and legs than me? ..." However, the more arms and legs it has, the harder it runs and the farther it gets from its destination.
