Sharks stop moving when upside down because they enter a trance-like state called tonic immobility, a temporary paralysis triggered by disorientation or sensory overload, causing their muscles to relax and breathing to slow, though scientists still debate its exact purpose, with theories suggesting defense, mating, or sensory shutdown, but it's a natural reflex that helps researchers study them safely.
