It’s a common misconception that snakes don’t yawn, but this isn’t true! Snakes do indeed yawn, although why they do is still somewhat of a mystery. Some experts suggest that snakes may yawn in order to reset their respiratory systems and provide oxygen to their lungs in the same way humans do when they yawn. This could be especially important for reptiles since they can’t regulate their body temperature internally like mammals, so it might help them to cool down or warm up depending on the environment.
Why Do Snakes Yawn?
Snakes may yawn for a variety of reasons, including as a means of regulating their body temperature, to clear their airways, or as a sign of stress or boredom. It is not entirely understood why snakes yawn, but it may be related to their unique respiratory system and the fact that they do not have the ability to pant as mammals do. Some scientific studies also suggest that yawning in snakes may be related to their hunting behavior.

Yawning may help to stretch and relax these muscles, making it easier for the snake to swallow its food. Additionally, some studies suggest that yawning may also be a way for snakes to regulate their body temperature and metabolism following a large meal.
