Thermal Imaging and Thermoregulation in Endothermic Predators
Quick fact
Great white sharks and tuna have a network of blood vessels called the rete mirabile that acts like a biological radiator, keeping their core muscles warm—sometimes 20°C above the surrounding water—so they can hunt in cold, deep seas where prey are abundant.
Why this is interesting
Ever wondered how some predators can sense a warm meal from meters away, even in darkness or murky water? The secret lies in their ability to 'see' heat.
