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 the time in the trees. Its diet consists mainly of insects and small vertebrates. Frilled lizards or frillies as some call them also will eat plants as well although not commonly. The frill-necked lizard is a relatively large lizard, averaging 85 cm (2. 79 ft) in total length (including tail) and is kept as an exotic pet. The frill-necked lizard also was a major inspiration for the dilophosaurus shown in the movie Jurassic Park. And while Jurassic Park popularized them, these lizards do not share any other characteristics with the movie’s dinosaur save for their frill.
