Do Animals See Time Differently?

How do animals experience time? To a housefly, your hand moves in slow motion. To a Greenland shark, centuries pass like seasons. It’s a biological construction. The most subjective one that has ever existed. So what happens when different brains render the movie of reality at entirely different speeds? This video explores how different brains process subjective time across the animal kingdom. What's happening inside an insect's nervous system that allows it to easily dodge threats, how dogs use the slow, molecular decay of scent to track the passing hours of the day, and the physiological survival glitch that temporarily overclocks the human brain during a crisis, stretching seconds into minutes. We examine the deep-sea shark that measures its life in centuries, the mayfly that crams an entire lifecycle into a single day, and the neurological discovery of the "flicker fusion threshold" that shows us why time is not a universal constant. Neurology has a name for the visual processing rate that governs conscious experience. What we cannot answer is what the animal is actually experiencing when its clock is running on an entirely different operating system.
