25. It can detect the heartbeat of an immobile animal as well!
26. Though most sharks are poikilotherms (an animal whose body temperature changes with the change of temperature in the surroundings), Great White Shark regulates body temperatures in certain areas of its body like the stomach and hence is partially warm-blooded.
27. During migration to poor-nutrient areas, it uses its fat and oil deposits of liver to sustain.
