Generally speaking, crabs don't need to be killed. You just need to wash them. You must brush them with a brush, otherwise they will be dirty, and then turn them over and steam them.

Crabs spend most of their time looking for food. Generally, they are not picky eaters, and they can eat all the food they can get.

Small fish and shrimp are their favorite, but some crabs eat seaweed, even animal carcasses or plants.

Although the crab is small, it is all-sided. After removing the hard shell of the crab, we can find that the body part of the crab is protected by a shell. These shield-like shells are called carapace by biologists.

Crab body is symmetrical, which can be divided into forehead area, eye area, heart area, liver area, stomach area, intestine area and gill area. Both sides of the crab's body are connected by appendage. The appendages of the head are called tentacles, which have the functions of touch and smell. Some appendages have the function of mouth, which is used to tear food and send it into the mouth.
