Why are crocodiles not considered warm-blooded despite having a four-chambered heart?
1. They lack the ability to internally regulate their body temperature.
2. Their four-chambered heart is not efficient in thermoregulation.
3. They are warm-blooded, but their temperature regulation is different from mammals.
4. The four-chambered heart is only related to oxygenation of blood, not temperature regulation.
