Pangolins maintain body temperatures lower than most mammals, around 33°C (91°F). Metabolism is slower, consistent with an insect-based diet. Lower temperature conserves energy between meals. Nocturnal habits complement low metabolism. They avoid overheating in tropical climates. Lower body temperature may influence activity patterns.
It helps explain slow movements and nocturnal foraging.
Adaptations in metabolism suit dietary specialization.
Low temperature reduces energy demands for insect digestion.
