Genus Chlamydosaurus is commonly known as the frilled-neck lizard or frilled dragon. It is the only species in this genus and is characterized by the frill it displays around its neck, which is used for display and communication. While frilled dragon is the most commonly used synonym, some people refer to this reptile as the frilled lizard, frilled agama, or frilled-necked agama. Other synonyms include the Australian frilled lizard, the horned lizard, and the thorny devil. These synonyms are often used interchangeably with the frilled neck lizard, as they all refer to the same species in the Genus Chlamydosaurus.
