Characteristics of the chlamydosaurus

The most notable aspect of this animal is the frill of skin that surrounds its head which opens when it feels threatened. For this reason, it is also commonly called the “frilled-neck lizard.” It is surely familiar to you because of the famous dinosaur movie Jurassic Park. In one scene in this film, we can see how a Dilophosaurus wetherilli tries to attack one of the protagonists.

Male frilled lizards can grow to be quite a bit bigger than females. It has a lifespan of no more than six years and remains almost totally inactive during periods of drought, which allows it to decrease its dietary needs.

Habitat of the chlamydosaurus

The chlamydosaurus lives in northern Australia and southern Papua New Guinea in warm, moist climates. It spends most of its time in trees, lying in wait for its prey.


What does this reptile eat?

The frilled lizard mainly eats insects and small vertebrates. It is an ambush predator, hiding in trees and stalking its prey. It has a highly developed sense of sight, which helps it easily catch insects.


Chlamydosaurus reproduction

Mating season lasts from September to October and the eggs hatch between December and January, three months after being laid. Females tend to give off a strong scent to attract males, who tend to be very aggressive with each other.


The frilled neck serves as a method of communication and is used during mating to attract females.

Fun facts about the chlamydosaurus

If the chlamydosaurus feels threatened, it will first try to camouflage itself with its surroundings. If this does not work, it can become very aggressive, rising up on its back legs, opening its mouth, and spreading its frill to appear much larger. In addition, it usually hisses and runs towards its enemy to attack it.

If this does not work and the attacker does not feel threatened, the Chlamydosaurus kingii will run away and hide.
