How do sharks maintain bady temperature?

Sharks are primarily ectothermic, meaning they rely on the surrounding water to regulate their body temperature. However, some species, like the great white shark and the mako shark, have specialized adaptations that allow them to retain heat. They possess a unique vascular structure known as the rete mirabile, which helps conserve metabolic heat generated during activity, allowing them to maintain a body temperature that is warmer than the surrounding water. This adaptation enhances their agility and efficiency in hunting in colder waters.
