If you have a backyard in Australia and are curious about the local reptilian residents, this listicle is for you. Whether you’re a homeowner, nature enthusiast, or someone interested in observing Australian wildlife, knowing the common backyard lizards can enhance your outdoor experience. Here, we explore ten prevalent lizard species you might encounter in your garden or backyard, detailing their appearance, habits, and why they’re worth appreciating.
Common Blue-tongue Skink
The Blue-tongue Skink (Tiliqua scincoides) is a large, slow-moving lizard renowned for its distinctive bright blue tongue, which it displays as a defense mechanism. They typically grow up to 50 cm long and have a shiny, smooth body with brown and cream banding, making them easy to identify. These skinks are beneficial in gardens because they feed on insects, snails, and even small rodents, helping control pests naturally.
The Eastern Water Dragon (Intellagama lesueurii) is a semi-aquatic lizard often seen basking on rocks or tree branches near water bodies in eastern Australia. Adults can reach up to 1.2 meters in length, featuring a robust body, spiny crest along their back, and a long tail. They are excellent swimmers and often hunt for insects, small fish, and frogs, making them an intriguing addition to backyard ponds or water features.
The Jacky Dragon (Amphibolurus muricatus) is a small to medium-sized lizard, usually around 30-45 cm long, known for its vibrant coloration and active behavior. They have a distinctive crest on their head and are often seen perched on rocks or shrubs. Jacky Dragons are insectivorous and help keep your backyard free of pests, plus their lively antics make them a joy to observe.
Similar to its eastern cousin, the Centralian Blue-tongue Skink (Tiliqua multifasciata) is native to arid central Australia. It features a robust body with a tan or brown base color and dark banding, and like other blue-tongues, it sports a bright blue tongue for defense. These skinks are ground dwellers, often hiding under rocks or logs, and they play a vital role in controlling insects and small invertebrates in dry backyard settings.
The Shingleback (Tiliqua rugosa) is a distinctive, chunky blue-tongue skink with a short, stumpy tail that resembles a second head. Its scales resemble shingles on a roof, giving it a rugged appearance. They are slow-moving and often seen basking in the sun or foraging for fungi, insects, and plants. Their docile nature makes them a popular backyard visitor, provided you respect their space.
The Garden Skink (Morethia boulengeri) is a small, slender lizard commonly found in Australian backyards, especially in gardens with plenty of leaf litter and rocks. It measures around 15-20 cm and has a brown or grey coloration that provides excellent camouflage. These skinks are insectivores and contribute to pest control, making them beneficial residents for a healthy garden ecosystem.
The Eastern Bearded Dragon (Pogona barbata) is a popular reptile among backyard enthusiasts due to its friendly nature and striking appearance. They grow up to 60 cm long, with a broad head, spiny throat, and a beard that puffs out when threatened or displaying dominance. Bearded Dragons are omnivorous, eating insects, small animals, and vegetation, and are often seen basking in sunny spots in the yard.
The Mallee Dragon (Ctenophorus fordi) is a smaller, ground-dwelling lizard native to arid regions of southern Australia. It measures around 20-30 cm and has a sandy or reddish coloration that blends into its environment. Mallee Dragons are active during the day, hunting insects and small invertebrates, and are admired for their agility and striking appearance.
The Thorny Devil (Moloch horridus) is one of Australia’s most iconic and unique lizards, famous for its spiny, armor-like appearance. Growing up to 20 cm, it is well-camouflaged among desert plants and has a diet primarily consisting of ants. While they are more common in arid zones, Thorny Devils can sometimes be found in backyard gardens if the environment mimics their natural habitat, making them a fascinating species to learn about.
How to Choose
When selecting which backyard lizard species you might want to encourage or observe, consider factors like your local climate, available habitat, and how much interaction you desire. Some species, like Blue-tongue Skinks and Bearded Dragons, are larger and more tolerant of human presence, while others, such as garden skinks or skinks in general, are more reclusive. Also, think about the role they play in your garden ecosystem—predators of pests or indicators of healthy habitat—and ensure your environment provides the necessary shelter, water, and food sources to support them.
