The FRILLED-NECKED LIZARD – listed as “Least Concerned” Posted on 29 Jan 21:01

Written by: Tzar the Paddington Poodle.

  An iconic lizard, the Frilled-neck is Australia’s version of a dragon, all be it in miniature. They are perfectly harmless. Featuring in my books The Adventures of Tzar the Paddington Poodle, Cattle Dog Encounter and Brahman Bull Encounter, scheduled for release June 2017 these tiny lizards snap open their frills when they are frightened, and it gapes its mouth, exposing a bright pink or yellow lining; it spreads out its frill, displaying bright orange and red scales; raises its body; and sometimes holds its tail above its body. This reaction is used for territorial displays, to discourage predators, and during courtship

Conservation Status of the Frilled-Necked lizard:

  • Various threats are likely to be causing declines in this species. Late dry season fires in the Northern Territory were responsible for an approximate 30% mortality rate in a small monitored population in Kakadu National Park, though no mortality was recorded in the early dry season fires (Griffiths 1994). Local population declines have also been reported after the arrival of the cane toad, Rhinella marina (Breeden 1963). Predation by cats has also caused declines in this species (Brook et al. 2004). In the Trans-Fly region of New Guinea, this species is reported to be "highly sought after for the pet trade" (Allison 2006).
  • The Frilled-Necked lizard, has been assessed as Least Concern owing to its large distribution. There are a number of localized threats causing small population declines, however, these are not impacting over large parts of this species' range. Monitoring should continue as an increase in threat levels and therefore population decline will trigger a threat category in the future.

Here are a few facts about these interesting creatures:

  • The Frilled-Necked lizards are endemic to the northern regions of Australia and southern regions of New
  • A frill-necked lizard was featured on the reverse of the Australian 2-cent coin until 1991.
  • A frill-necked lizard, known as "Lizzie," was the mascot for the 2000 Paralympic Games.
  • The emblem of the Australian Army's Regional Force Surveillance Unit, NORFORCE (North-West Mobile Force) of the Kimberleys and Northern Territory is the frill-necked lizard.
  • Because of its unique appearance and behaviour, the frilled-necked lizard is commonly used in film and television.
  • A frilled-necked lizard named Frank appears in the Disney film The Rescuers Down Under. 
  • In the film Jurassic Park, the dinosaur Dilophosaurus was portrayed with a fictional neck frill, which was raised during attack, similar to that of a frilled-neck lizard. The movie generated an increase in demand for frill-necked lizards as pets. 
  • In the CGI animated film Blinky Bill the Movie Jacko a frill-necked lizard wears a black t-shirt voiced by David Wenham.
