Menetia greyii
oviparous (lays eggs), parthenogenesis
The common dwarf skink (Menetia greyii), also known as Grey's skink, is a widespread and abundant lizard native to mainland Australia and parts of Indonesia. This small, burrowing species is found in diverse habitats including heaths, deserts, woodlands, grasslands, and urban environments. It is distinguished by its smooth scales, elongated brownish-grey body, and distinctive dorsal dashes and lateral stripes, with breeding males exhibiting a yellow/orange flush on their underbelly.

About Menetia greyii
Menetia greyii: The Common Dwarf Skink
The common dwarf skink, scientifically known as Menetia greyii and also referred to as Grey's skink, is a small, ubiquitous lizard species found across much of mainland Australia and extending into parts of Indonesia. It is one of the most abundant lizard species on the continent, demonstrating remarkable adaptability to a wide range of environments.
Habitat and Distribution
Menetia greyii thrives in diverse habitats, including heaths, deserts, woodlands, and grasslands. Its adaptability is further highlighted by its frequent presence in urban environments, making it a familiar sight to many. These skinks typically seek shelter beneath logs and rocks and are often observed foraging through leaf litter in search of their prey. Their range covers approximately 93% of the Australian continent, excluding only the north-east Northern Territory, Cape York Peninsula, southern Victoria, and Tasmania.
Physical Description and Behavior
This species is characterized by its very small size, with adults typically measuring between 38 to 40 mm in snout-to-vent length. They possess an elongated, slender body covered in smooth scales. The coloration is generally brownish-grey to grey, marked by dorsal dashes that can form broken lines, alongside broad dark upper lateral stripes and distinct white midlateral stripes. The underbelly is usually white, though adult males can develop a yellow or orange flush on their underbelly and a pink flush on their throat during the breeding season. Menetia greyii is a fossorial species, meaning it spends time burrowing, and is diurnal, being most active during daylight hours.
Diet and Reproduction
The diet of the common dwarf skink consists primarily of small invertebrates, such as ants, termites, and small spiders. A particularly fascinating aspect of Menetia greyii's biology is its reproductive strategy. The species is known to reproduce through both sexual reproduction and parthenogenesis. Parthenogenesis, the development of an embryo from an unfertilized egg, allows for the creation of clones of the female parent. Adult females typically lay one to three eggs per clutch.

What kind of habitats does Menetia greyii prefer?
This species is highly adaptable and inhabits a variety of environments, including heaths, deserts, woodlands, and grasslands. It is also frequently encountered in urban settings and shelters under logs and rocks.
What does the common dwarf skink eat?
The diet of Menetia greyii primarily consists of small invertebrates. This includes small insects such as ants and termites, as well as small spiders.
How does the common dwarf skink reproduce?
Remarkably, Menetia greyii is capable of reproducing through both sexual reproduction and parthenogenesis. Parthenogenesis allows eggs to mature without fertilization, resulting in clones of the female.
What are the physical characteristics of Menetia greyii?
Menetia greyii is a very small skink with an elongated, light-built body covered in smooth scales. It is typically brownish-grey to grey with dorsal dashes and prominent dark upper lateral and white midlateral stripes. The underbelly is usually white, with breeding males displaying a yellow/orange flush.
Is the common dwarf skink active at night?
No, the common dwarf skink is a diurnal species, meaning it is active during the daytime. It is also a fossorial lizard, spending time burrowing.

Lacertilia
Lizards are a diverse group of reptiles, encompassing over 7,000 species found on every continent except Antarctica. They exhibit a wide range of sizes, from tiny chameleons to the massive Komodo dragon, and possess characteristics like scales, four limbs (though some are legless), and long tails. Lizards inhabit nearly every environment, from deserts to rainforests, and play crucial roles as both predators and prey within their ecosystems.
Lampropholis delicata
The delicate skink, Lampropholis delicata, is a small, diurnal lizard native to Eastern Australia, known for its color dimorphism and smooth scales. It inhabits a variety of moist environments, including woodlands, heaths, and rainforests, and has become an invasive species in New Zealand and Hawaii, often found in suburban gardens. This skink is an opportunistic insectivore, preying on spiders, bees, larvae, and termites, and is notable for its ability to shed and regenerate its tail as a defense mechanism.
Lerista praepedita
The western worm lerista (Lerista praepedita) is a slender skink species found in coastal heath and woodlands of Western Australia. It is characterized by its lack of front legs, extremely small hind legs, and distinctive dark brown stripes along its sides.
