The class Actinopterygii, which includes most bony fish, is primarily ectothermic, meaning they rely on external environmental temperatures to regulate their body heat. However, some species within this class, such as certain tunas and billfish, exhibit regional endothermy, allowing them to maintain higher body temperatures in specific tissues, which enhances their swimming performance and metabolic efficiency. Overall, the majority of actinopterygian fish do not possess true endothermic capabilities.
