A Correct answer
Explanation

Crocodiles are reptiles and lack sweat glands entirely. They pant and open their mouths to release excess body heat through evaporative cooling from their mouth lining, a behavior called gaping.

AI explanation

To answer this question, we need to understand the thermoregulation mechanism in crocodiles.

Option A) True - This option is correct. Crocodiles do not have sweat glands like humans do. Instead, they use their mouths to release heat. When crocodiles open their mouths, heat is released through evaporation from the wet surfaces inside their mouths. This behavior is known as gaping and helps them regulate their body temperature.

Option B) False - This option is incorrect. Crocodiles do not use their mouths to release heat just for feeding purposes. The main purpose of gaping is to release heat and regulate their body temperature.

The correct answer is A) True. Crocodiles have no sweat glands, so they use their mouths to release heat through gaping.
