Crocodiles are ectotherms which means that they get heat from their surroundings. While their blood is not necessarily “cold”, they do need to regulate their temperature by basking in the sun, moving to warm water and resting on something that radiates heat. If they get too hot they will seek shade or move into cooler water. Crocodiles do not have sweat glands, and release heat through their mouths.
