Crabs have eight legs, that is, their eight feet. These eight legs are evenly distributed on both sides of the body, with four on each side. Because of the special structure of gait, joints can only move up and down, so these gaits can only help crabs move left and right, but not back and forth. Besides walking feet, crabs have two claw feet, which are mainly used for digging holes, defending and attacking. Because their main function is not activity, these two pliers can't be counted as their legs. First, does a crab have legs? Crabs are animals that we can often see, and they are very common in daily life. Whether in water or on land, we can easily see the activities of crabs. Crabs have legs, which are evenly distributed on both sides of the body and can play an important role in activities. Like the legs of other animals, the legs of crabs are mainly used for activities, and can also support them to complete some more complicated activities, such as predation and so on.

Second, how many legs does a crab have? As mentioned above, crabs have legs. They have more legs than humans and most mammals. Crabs have eight legs, which are evenly distributed on both sides of their bodies. These eight legs have another name, called "walking feet", which means walking. The gait structure of crabs is quite special. Most crabs can only move left and right, not back and forth, so from the outside, crabs walk sideways.

Many people think that crabs have 10 legs, because crabs have two claws besides the eight feet mentioned above. The function of pincers is also very important. They can dig holes and have many functions such as defense and attack. Although they have many functions, their main function is not exercise, so strictly speaking, these two pliers are not their legs.
