Sharks enter a trance-like state called tonic immobility when flipped upside down, which decreases their sensory responsiveness and pain sensitivity. This behavior is used by scientists for safe research and may serve various evolutionary purposes, though its exact function remains uncertain.
A recent study suggests that sharks' tendency to freeze when turned upside down, known as tonic immobility, is likely an evolutionary relic rather than an adaptive survival strategy, with many species having lost this trait over millions of years due to environmental pressures.
