males also disperse further from their hatching area. The species reaches sexual maturity within two years; males live up to six years compared to four years for females. Conservation The International Union for Conservation of Nature lists the frilled lizard as of least concern, due to its abundance and wide range, but warns that its population may be locally declining in some areas. It is a popular species in the pet trade, which may threaten some wild populations. Most pet lizards appear to come from Indonesia, as export of them is banned in Australia and Papua New Guinea. Being difficult to breed in captivity, many presumed captive bred lizards are likely to have been taken from the wild. Frilled lizards may also be threatened by feral cats, though they do not appear to be significantly affected by the invasive cane toad. Relationship with humans The frilled lizard is considered to be among the most iconic Australian animals along with the kangaroo and koala. Archaeological evidence indicates that frilled lizards were eaten by some indigenous peoples in ancient times. In the late 19th century, William Saville-Kent brought a live lizard to England where it was observed by fellow biologists. Another specimen was kept at a reptile display in Paris, as reptiles were becoming more popular in captivity. Because of its unique appearance and behaviour, the creature has often been used in media. In Steven Spielberg's 1993 film Jurassic Park, the dinosaur Dilophosaurus was portrayed with a similar neck frill that rose when attacking. Its image has been used in the 1994 LGBT-themed film The Adventures of Priscilla, Queen of the Desert. The species has been featured on some Australian coins.
