Four sharp knives and two iron tongs, dressed in armor, run wild all over the world. "Do you know what animal this is? Yes, it's a crab.

My mother bought some Yangcheng Lake hairy crabs the other day, and I kept them in a bucket. Hairy crabs are blue-brown, and their two small eyes are black and bright, which can rotate 360 degrees like a tie-rod antenna on TV. A small mouth keeps blowing a string of pearl-like bubbles. The crab's back is hard, like a shield in the hands of an ancient warrior. The belly is white and has a round cover. It is said that this is its navel. There are eight slender legs on both sides of the body. The hair on the legs is yellow, and the claws at the proximal end are golden yellow and sharp. In addition, the front ends of the two front legs are two pliers like iron pliers. When you open the pliers, you can find that there are two rows of sharp sawtooth inside, which looks quite imposing. Green back, white belly, yellow hair and golden claws are the appearance characteristics of hairy crabs.
