Description of Ctenotus nigrilineatus

Common Name: Ctenotus nigrilineatus
Scientific Name: Ctenotus nigrilineatus

Habitat

The Ctenotus nigrilineatus, commonly known as the black-lined ctenotus, is primarily found in southern Australia, notably in arid and semi-arid regions. This species thrives in sandy and grassy environments, often inhabiting open woodlands, shrublands, and heathlands. Its geographical range includes areas in New South Wales and Victoria, where it prefers habitats with ample ground cover to provide shelter and foraging opportunities.

Physical Characteristics

Measuring around 70 to 80 millimeters in total length, Ctenotus nigrilineatus displays distinct coloration that aids in its camouflage. The body is slender with a flattened head. Its most notable feature is the contrasting dark stripes that run along its back, which can vary in color from light brown to grey. These stripe patterns are key identifiers of the species. Additionally, their scales are smooth and provide a polished appearance, which is typical for many lizard species in the Ctenotus genus.

Behavior

Ctenotus nigrilineatus exhibits diurnal behavior, meaning it is active during the day. This species is known for its quick movements, making it adept at escaping predators. It often basks in sunny spots to regulate its body temperature, and its agile nature allows it to navigate through vegetation with ease. The black-lined ctenotus is also known for burrowing and creating small dens, which provide refuge from extreme temperatures.

Diet

The diet of Ctenotus nigrilineatus primarily consists of small invertebrates. Common food sources include ants, termites, beetles, and other insects. This lizard exhibits opportunistic feeding behavior, usually foraging on the ground and occasionally climbing low vegetation to hunt. Its role as an insectivore helps control pest populations in its habitat, highlighting its importance in the ecosystem.

Reproduction

Ctenotus nigrilineatus typically breeds in the warmer months, with the breeding season occurring from late spring to early summer. Females lay clutches of eggs in sandy substrates, which are incubated for several weeks before hatching. Offspring are born fully formed and are independent from birth. Parental care is minimal, with lizards quickly dispersing to establish their own territories post-hatching.

Conservation Status

The conservation status of Ctenotus nigrilineatus is currently listed as Least Concern by the IUCN. However, habitat loss due to urban development and agriculture poses potential threats to its populations. Continuous monitoring is essential to ensure that this species does not face increased risks in the future.

Interesting Facts

One fascinating aspect of Ctenotus nigrilineatus is its remarkable adaptability to fluctuating environmental conditions. Research indicates that this species can thrive in disturbed habitats, demonstrating resilience against habitat alteration. Additionally, it has an exceptional ability to regenerate its tail if lost, an important feature that aids in survival against predation.

Role in Ecosystem

The black-lined ctenotus plays a vital role in its ecosystem by maintaining the balance of insect populations through its feeding habits. As a prey species, it also serves as an important food source for larger predators, including birds of prey and snakes. Its burrowing behavior contributes to soil aeration and nutrient cycling, enhancing the health of the habitats it occupies.
