Often this is all bluff and if they don't get their way will usually flee in the opposite direction with speed. They have powerful back legs and are very capable runners on two legs.
Compared to other dragon species found in Australia, the Frill neck is a large dragon and can obtain a total length up to a metre.
When observed in the wild they are usually seen hugging against vertical or slopping tree branches or trucks where their colouration helps them suitably camouflage. Once aware of presence, they will always maneuver their body to the opposite side mostly out of view from their perceived threat where they cryptically keep an eye out.
Frill necks are found right across the tropical top end of Australia and prefer areas of dry sclerophyll forests and savanna woodlands.
In captivity when they are seeking refuge, I have noticed that they seem to prefer the thick grass instead of hollow logs.
In the wild they prey upon small lizards, small mammals, birds and various insects including ants of which they consume large numbers of. In captivity we often observe them picking out the pieces of meat from the food prepared for the blue tongue lizards in our communal pit.
Females can lay up to 14 eggs in a single clutch and hatchlings emerge anywhere between 60 and 90 days. Successful incubation temperatures have been recorded from 27 to 30 degrees Celsius.
A very popular lizard in captivity but they have a reputation for suffering stress and it is recommended where possible to purchase captive bred specimens over wild caught unless they have some successful captive history.
The most commonly kept Frill necks are the Queensland form which generally speaking are not as colorful as specimens found in the Northern territory or Western Australia. Now that many more W.A specimens are being legally collected this is likely to change.
All native reptiles in W.A they remain protected under the W.A Wildlife Conservation Act (1950)
