Oedura rhombifer
Severely endangered·Oviparous (egg-laying)
Oedura rhombifer, commonly known as the zigzag velvet gecko, is a lizard species endemic to Australia. It is characterized by its light brown to darker brown coloration with a distinctive zigzag pattern along its sides and tail, likely an adaptation for camouflage. This arboreal gecko typically inhabits wooded areas and can be found under tree bark or in proximity to human structures, but it is considered a rare and severely endangered species.

About Oedura rhombifer
Oedura rhombifer: The Zigzag Velvet Gecko
Oedura rhombifer, commonly known as the zigzag velvet gecko or the zig-zag gecko, is a species of lizard belonging to the Diplodactylidae family. This gecko is endemic to Australia, found primarily in northern regions such as the Kimberley in Western Australia and extending up to northern Queensland, with some reports from the Alice Springs region.
Description and Habitat
The zigzag velvet gecko is a small reptile, capable of reaching a total length of up to 16 centimeters (approximately 6.3 inches), including its tail. Its coloration provides effective camouflage: it is light brown on its back, transitioning to a darker brown on its sides, and a pale white or off-white on its underside. This coloring, combined with speckles or darker tones on its limbs, creates a striking zigzag pattern along its flanks and tail. The species typically inhabits wooded environments, where it can be found sheltering under the bark of decaying trees. Interestingly, it has also been observed adapting to areas with human-generated rubbish or even in proximity to buildings.
Behavior and Reproduction
While generally considered an arboreal species, meaning it lives in trees, Oedura rhombifer is also known to seek refuge beneath ground litter. This behavior suggests a degree of flexibility in its habitat use. The reproduction method of the zigzag velvet gecko is oviparous, meaning it lays eggs.
Conservation Concerns
Oedura rhombifer is recognized as a rare and severely endangered species. Its population has faced significant decline, with a notable absence of recent records until a few specimens were discovered in New South Wales in 2002. The primary threats contributing to its endangered status include extensive habitat loss driven by logging activities and bush fires. Furthermore, introduced predators such as foxes and feral cats pose a considerable danger to the gecko's survival. The isolation of its populations also results in a critical lack of genetic variability, making the species less resilient to environmental changes and diseases. Conservationists warn that without urgent intervention, the zigzag velvet gecko faces a high risk of extinction.

This species is endemic to Australia, with its known distribution in northern Australia. It has been recorded in the Kimberley region of Western Australia and up to northern Queensland, with some sightings reported in the Alice Springs region.
What kind of habitat does Oedura rhombifer prefer?
The zigzag velvet gecko prefers wooded habitats. It is often found seeking shelter under the bark of deteriorating trees, but has also been observed in areas with rubbish or even near buildings.
Is Oedura rhombifer a common species?
No, Oedura rhombifer is considered a rare species. Until 2002, there were no recent records of the gecko, highlighting its elusive nature and potentially declining population.
What are the main threats to Oedura rhombifer?
The species faces significant threats including habitat loss due to logging and bush fires. Introduced predators like foxes and feral cats also pose a danger. Additionally, the isolation of its populations leads to a lack of genetic variability, further endangering the species.

Anolis carolinensis carolinensis
The Anolis carolinensis, commonly known as the green anole or Carolina anole, is a small to medium-sized lizard native to the southeastern United States. It is distinguished by its ability to change color from shades of brown to green, a trait that leads to its common nickname 'American chameleon,' though it is not a true chameleon. These arboreal lizards inhabit forests, grasslands, and can even adapt to urban environments with sufficient vegetation and insect prey.
Brookesia antakarana
The Antakarana leaf chameleon, *Brookesia antakarana*, is a species of chameleon found exclusively in Madagascar. This lizard is known for its leaf-like appearance, which aids in camouflage within its natural habitat.
Chinese water dragon
The Chinese water dragon is a large, diurnal lizard native to subtropical forests in southern China and Southeast Asia. These semi-arboreal reptiles are known for their green coloration, prominent crests in males, and their reliance on unpolluted streams for escape and habitat. Their diet primarily consists of arthropods, but they are omnivorous and will consume vertebrates and plants.
