Why are tiger sharks cold blooded?

Tiger sharks, like all sharks, are actually ectothermic, meaning they are cold-blooded. This allows them to maintain their body temperature based on their surrounding environment, which helps them conserve energy. However, some species of sharks, including the tiger shark, have adaptations that enable them to slightly regulate their body temperature in warmer waters, but they rely primarily on the ambient temperature of their habitat. This cold-blooded nature is typical of many fish species, allowing them to thrive in diverse aquatic environments.
