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 yellow 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 is a relatively large lizard, growing up to 85 centimetres (2.79 ft). 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.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
