Frilled lizards australian danger

The frill-necked lizardhref=" (Chlamydosaurus kingii)"> (Chlamydosaurus kingii), also known as the frilled lizard or frilled dragon, is found mainly in northern Australia and southern New Guinea. Its name comes from the large frill around its neck, which usually stays folded against t lizard's body. It is largely arb, spending the majority of the time in the trees. The lizard's diet consists mainly of insects and small vertebrates. The frill-necked lizard is a relatively large lizard, reaching up to 91.4 cm in length. It may also be kept in captivity.Description
The frill-necked lizard is so called because of the large ruff of skin which usually lies folded back against its head and neck. The neck frill is supported by long spines of cartilage which are connected to the jaw bones. When the lizard is frightened, it gapes its mouth, exposing a bright pink or y lining; the frill flares out as well, displaying bright orange and red scales. This reaction is often used to discourage predators or during courtship. The lizard is a member of the agamid family. It a relatively large lizard, growing up to 91.4 cm. The lizard is also capable of bipedal locomotion.

The frill-necked lizard does not have a standard colour; however, it is characterised by a body that is darker than its frill. There is only one recorded species of the frill-necked lizard; however, the immense variations of colour among the species has led some scientists to hypothesise more than one species.

HabitatThe frill-necked lizard is found mainly in the northern regions of Australia and southern New Guinea. The lizard inhabits humid climates such as those in the tropical savannah woodlands. The frill-necked lizard is an arboreal lizard, meaning it spends a majority of its time in the trees. The lizard ventures to the floor only in search of food, or to engage in territorial conflicts.[citation needed] The arboreal habitat may be a product of the lizard's diet, which consists mainly of small arthropods and vertebrates (usually smaller lizards).[citation needed] However, the trees are most importantly used for camouflage. There is not one standard colour: rather, colouration varies according to the lizard's environment. For example, a lizard found in a dryer, clay filled environment will most likely have a collage of oranges, reds, and browns; whereas a lizard found in a damper, more tropical region will tend to show darker browns and greys. This suggests that the lizards use their habitats for protection in the form of camouflage.Diet
Like many lizards, frill-necked lizards are insectivorous, feeding on cicadas, beetles, and termites. They especially favour butterflies and moths, their larvae even more so.Though insects are their primary source of food, they also consume spiders, other lizards, and small mammals. Like most members of the agamids (dragons), frill-necked lizards employ an ambush method of hunting, lying in wait for their prey. When the lizards eat, they eat in abundance; these binge periods usually occur during the wet season, when the lizards will ingest hundreds to thousands of alates (ants or termites).
