What does it mean when a beardie is basking and sits with it's mouth open? Looks kind of like the thumbnail for Cheri S. I know what we have isn't a beardie, but enough similarities that it must be from the same family. Going to the vet tomorrow at 9:30 so hopefully know for sure what it is then. Meantime, is it a sign that he's hungry if he sits with his mouth open (usually looking up at the heat light)?
It usually means they're too warm. Most reptiles (anoles, beardies and even crocs & gators) will sit there with their mouths open to cool off. Sometimes it can hint at a repiratory infection, but if they're only doing it under their basking spot, it's probably just thermoregulation
