I too would love to know more on this.... When I first joined the forum in 2018 the only thing everyone said was gaping was bad...Yeah it is a big difference lol! As far as gaping goes I know it's to regulate temp but at what point does it be come dangerous when there are no issues/signs of RI? I don't really know the physiology or process of thermoregulation of reptiles in general when they try to "cool down". Sorry to sound uneducated lol! I am very curious because my chameleons live outdoors and I do have concerns with overheating excessive gaping etc.
