Bearded dragons go through brumation when the temperature goes below 15.5–21.0☌ (60–70☏) during the night and 24.0–26.5☌ (75–80☏) during the day for 8-10 hours. When temperatures are extreme, a very small range of temperatures exists through which the reptile's bodies can stay active and where their bodies cannot tolerate the extreme heat and they die. Reptiles go dormant in the hottest temperatures, but it differs from brumation during cooler temperatures. īearded dragons go through a type of hibernation called brumation, in which like hibernation, reptiles go months without eating, but sporadically drink water. They can be found on fallen/broken trees, rocky outcrops, and bushes when basking. This is also linked to dominance behavior and competition for territory/basking areas. They are considered to be semiarboreal and quite readily climb and bask at height. Their range extends throughout the interior of the eastern states to the eastern half of South Australia and southeastern Northern Territory. They live in the arid and subtropical woodlands, scrublands, savannas, and shore areas, and into the great interior deserts.
Males grow up to 60 cm (24 in) long, and females up to 51 cm (20 in).īearded dragons originate from deserts and other dry areas in Australia, with the various species occupying slightly overlapping areas of the landmass. Bearded dragons occur in a variety of colors and morphs and can range from being all dark to completely white under controlled breeding conditions. Some have the ability to slightly change color during rivalry challenges between males, in response to ambient temperature changes such as turning black to absorb heat, and other stimuli. Bearded dragons display a hand-waving gesture to show submission (most often when acknowledging another bearded dragon's territory), and a head-bobbing display to show dominance between dragons. When threatened, bearded dragons puff up their bodies and beards to ward off predators and make their somewhat dull spikes seem somewhat more dangerous. Bearded dragons are characterized by their broad, triangular heads, flattened bodies, and rows and clusters of spiny scales covering their entire bodies. The genus Pogona is in the subfamily Amphibolurinae of the lizard group Agamidae. Captive adult measuring over 30 cm (1 ft) Galore Hill Nature Reserve, New South Wales, Australia Skeleton at the Museum of Osteology in Oklahoma City, Oklahoma, United States They are found throughout much of Australia and inhabit environments such as deserts, and shrublands.
Their diet consists primarily of vegetation and some insects. Pogona species bask on rocks and exposed branches in the mornings and afternoons and sleep at night, making them a diurnal species. They are a semiarboreal species, spending significant amounts of time on branches, in bushes, and near human habitation. The name "bearded dragon" refers to the underside of the throat (or "beard") of the lizard, which can turn black and puff up for a number of reasons, most often as a result of stress, if they feel threatened, or are trying to entice a mate. Pogona is a genus of reptiles containing eight lizard species, which are often known by the common name bearded dragons. Genus of lizards commonly known as bearded dragons
