The movement of crab legs plays a crucial role in ventilating the gills. As crabs move their legs, they create water currents that help to draw water over the gills, facilitating gas exchange. This movement ensures that oxygen from the water is absorbed into the bloodstream while carbon dioxide is expelled. Additionally, the rhythmic movement aids in keeping the gills clean and free from debris.
