Let me share with you a difference between cold blooded and warm blooded.
| Aspect | Cold-blooded | Warm-blooded |
| Known as | Ectotherms | Endotherms |
| Thermal regulation | Rely on external sources (environment) for heat; behaviorally regulate temperature through basking, seeking shade, etc. | Body temperature, often maintaining a constant rate higher than the environment |
| Metabolic rate | Metabolic rate fluctuate in cooler environments and warmer environments | Metabolic rate is relatively constant |
| Energy efficiency | Generally more energy-efficient in maintaining metabolic functions when external temperatures are suitable | Requires more energy to maintain a constant internal temperature, especially in varied or extreme environments |
| Activity levels | More active in warmer conditions and less active in cooler conditions | Can maintain consistent activity levels across a range of environmental temperatures |
| Behavioral adaptations | Some species may enter a state of torpor or hibernation in colder conditions | Insulation (fur, feathers), sweating, and panting are common adaptations |
| Mode of regulation | Ectotherms might regulate temperature by basking in the sun or seeking shade | Endotherms regulate temperature through internal mechanisms such as shivering, sweating, or adjusting blood flow to extremities |
| Examples | · Reptiles (snakes, lizards) · Amphibians (frogs, salamanders) · Most fish | · Birds and mammals
