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. However, since having an open mouth is common behavior for bearded dragons, it's normally just a sign that they are regulating their heat.
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.
Landrace dogs have more variety in their appearance than do standardized dog breeds. An example of a dog landrace with a related standardized breed with a similar name is the collie. The Scotch Collie is a landrace, while the Rough Collie and the Border Collie are standardized breeds.owever, 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.
