Trivia: How do saltwater crocodiles cool off during the hot Australian summers?
Sweating
Opening their mouths
Swinging their tails
Rolling in mud
The correct answer is Opening their mouths
So why is this answer correct? : Images often show crocodiles basking in the sun on a riverbank with their mouths gaping. Scientists have discovered that this is a way to reduce their inner body temperature. Crocs are cold-blooded, so they can’t sweat and regulate their temperature as other animals can. Of course, they also move into the shade or cold water to cool off, but this is by far their most interesting method.
