Yacare caiman basking and gaping Crocodilians are ectotherms ('cold-blooded'), relying totally on their surroundings to control their system temperature. The principle implies of warming is sun's warmth, whilst immersion in h2o may possibly possibly elevate its temperature by means of thermal conduction or great the animal in scorching weather.
