How can crabs move if all they have inside is pure meat?
Crabs are fascinating creatures that have a unique way of moving. They do not have any bones or muscles, so they rely on their hydraulic system to move. This system is made up of a series of chambers that are filled with fluid. When the crab wants to move, it pumps fluid into one of the chambers, which causes the limb to extend. When the crab wants to stop moving, it releases the fluid, which causes the limb to retract.
In addition to their hydraulic system, crabs also have a set of muscles that they use to control their claws. These muscles are very strong, and they allow the crab to crush its prey.
Crabs are able to move in a variety of ways. They can walk, run, swim, and even climb. They are very agile creatures, and they can move quickly when they need to.
