Why Frilled Lizards Are Not for Beginner Pet Owners
The Frilled Lizard is one of the most fascinating reptiles in the world, instantly recognizable by the large frill around its neck. Native to Australia and New Guinea, this unique reptile has become increasingly popular among exotic pet enthusiasts. However, keeping a frilled lizard as a pet requires proper knowledge, space, and commitment. In this guide, we’ll explore everything you need to know about the frilled lizard, including its habitat, behavior, diet, and complete care requirements as a pet.
What Is a Frilled Lizard?
The Frilled Lizard (Chlamydosaurus kingii) is a medium to large arboreal lizard best known for its dramatic frill. When threatened, it opens its mouth and expands the frill to appear larger and scarier to predators. This defense display makes it one of the most iconic reptiles in the animal kingdom.
Frilled lizards can grow up to 35 inches long, including their tail, and typically live 10–15 years in captivity when cared for properly.
Natural Habitat and Behavior
In the wild, frilled lizards live in tropical forests, savannas, and woodlands of northern Australia and southern New Guinea. They are arboreal, meaning they spend much of their time in trees. These lizards are diurnal (active during the day) and prefer warm climates with moderate to high humidity.
Despite their intimidating appearance, frilled lizards are generally shy and non-aggressive. They prefer to flee rather than fight and rely on their frill mainly for defense.
Can Frilled Lizards Be Kept as Pets?
Yes, frilled lizards can be kept as pets, but they are best suited for experienced reptile keepers. Their large size, specific environmental needs, and sensitivity to stress make them challenging for beginners. Before getting one, always check local wildlife and exotic pet laws, as ownership may be restricted in some regions.
Frilled Lizard Housing Requirements
Proper housing is crucial for a healthy frilled lizard.
Enclosure Size
A tall and spacious enclosure is required. The minimum recommended size is:
-
6 ft tall x 4 ft wide x 3 ft deep
Vertical space is more important than floor space due to their tree-dwelling nature.
Temperature and Lighting
-
Basking temperature: 100–110°F (38–43°C)
-
Ambient temperature: 80–90°F (27–32°C)
-
Night temperature: Not below 75°F (24°C)
UVB lighting is essential for calcium absorption and bone health. Use a high-quality UVB bulb and replace it every 6–12 months.
Humidity
Maintain humidity levels between 60–70%. Mist the enclosure daily and provide live plants or a humidity box.
Diet and Feeding
Frilled lizards are omnivores, though juveniles are more insect-focused.
Insects
-
Crickets
-
Dubia roaches
-
Mealworms
-
Superworms
Plant Matter
-
Leafy greens (collard greens, mustard greens)
-
Vegetables (squash, carrots)
-
Occasional fruits (papaya, berries)
Dust insects with calcium and vitamin D3 supplements 2–3 times per week to prevent metabolic bone disease.
Handling and Temperament
Frilled lizards do not enjoy frequent handling. Excessive handling can cause stress, leading to appetite loss or illness. If handling is necessary, keep it minimal and gentle. Over time, some individuals may become tolerant of limited interaction.
Common Health Issues
Some common health problems include:
-
Metabolic Bone Disease (due to lack of UVB)
-
Dehydration
-
Respiratory infections
-
Parasites
Regular check-ups with a reptile veterinarian are highly recommended.
