Normally the bearded dragons will do this when they are basking under the heat lamp. Bearded dragons will also have their mouth open if they have a respiratory disease.

Landrace. A landrace is a local variety of a domesticated animal or plant species which has developed largely by natural processes, by adaptation to the natural and cultural environment in which it lives.hen an animal landrace is codified as a pedigree breed without significant selective breeding to alter it, though often to lock in its defining traits, it is often referred to as a natural breed or traditional breed by breeder and fancier organisations.
However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding. Landraces are distinct from ancestral wild species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock.owever, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding.
