They can smell other blood, but what about their blood?

The Great White Shark is interesting because its blood temperature is almost always warmer than the water surrounding it. Scientists say this allows for easier and faster digestion of food. This is due to its modified circulatory system, which is a bonus for being cold blooded. The heating up of he sharks anatomy is called regional endothermy, and works on places where most of the nerves are. This allows the big fish better vision, and movement due to heated muscle. Due to excess amounts of hemoglobin in the sharks blood, this is an indicator for a higher metabolism aswell.
