The frilled lizard (Chlamydosaurus kingii), also known commonly as the frill-necked lizard, frilled dragon or frilled agama, is a species of lizard in the family Agamidae. The species is endemic to northern Australia and southern New Guinea. This species is the only member of the genus Chlamydosaurus.
Its common names come from the large frill around its neck, which usually stays folded against the lizard’s body. C. kingii is largely arboreal, spending the majority of its time in the trees. Its diet consists mainly of insects and small vertebrates. Frill-necked lizards, or ‘frillies’ as some call them, will occasionally eat plants as well, although this behaviour is uncommon. It’s a relatively large lizard, averaging 85 cm (2.79 ft) in total length (including tail) and is kept as an exotic pet.
