How do crocodiles regulate their body temperature?

Crocodiles regulate their body temperature through behavioural adaptations, as they are ectothermic and cannot generate their own heat. They bask in the sun to warm up and submerge in water or seek shade to cool down. By opening their mouths, they increase heat loss through evaporation, a process called gaping. Crocodiles also adjust their activity levels, being more active when temperatures are optimal. These strategies allow them to survive in varying climates while maintaining their energy efficiency.
