The opening and closing of a mussel's shell are primarily controlled by a pair of adductor muscles. These muscles contract to close the shell tightly, protecting the mussel from predators and environmental stressors. When the muscles relax, the shell can open to allow for feeding and respiration. Additionally, environmental factors such as water currents and the presence of threats can influence the behavior of these muscles.
