Description

Ctenophorus gibba is a medium-sized lizard with a robust body and a tail longer than its body. The species displays sexual dimorphism, with males being larger and more brightly colored than females. [6] Typical coloration includes shades of brown and gray, with patterns that help it blend into its arid surroundings. [6] Adult Gibber dragons range in colour from yellowish-brown to reddish-brown to grey, with dark flecks. They are stout, with a round head, blunt snout, short limbs and tail. Adults have a total length (including tail) of 10.5–11.5 cm (4.1–4.5 in). [3] [4]

Habitat

Ctenophorus gibba is typically found in arid and semi-arid regions of central Australia. It prefers rocky outcrops and gibber plains, which provide ample basking sites and shelter from predators. [7]

Ecology and behaviour

This species is diurnal and primarily insectivorous, feeding on a variety of insects and other small invertebrates. Ctenophorus gibba is known for its territorial behavior, with males establishing and defending territories during the breeding season. [8] The Gibber dragon lives in the arid, sparsely vegetated gibber plains of northern South Australia. They bask on low protruding rocks and shelter in burrows dug into the soft soil between rocks. [3] [4]

Reproduction

Ctenophorus gibba breeds in the spring and summer months. Females lay clutches of 2-6 eggs, which are buried in sandy soil. The eggs hatch after an incubation period of approximately 60-70 days, depending on environmental conditions. [9]

Conservation Status

Currently, Ctenophorus gibba is not considered endangered. However, habitat destruction and climate change pose potential threats to its populations. Conservation efforts focus on habitat preservation and monitoring population trends. [10]

Ctenophorus mckenziei, more commonly known as the dwarf-bicycle dragon, is a species of endemic Australian lizard within the family Agamidae and genus Ctenophorus. Originally identified as the agamid Amphibolurus mckenziei, the lizard had been identified within the regions of Western Australia and South Australia in which it occupied the shrubbery and woodland areas as its habitat. It was subsequently transferred to the genus Ctenophorus along with other Agamid species in which it shared similar morphology and characteristics. The name mckenziei is in reference to Norman Leslie Mckenzie, who was a zoologist and discovered the existence of the lizard. Listed on the IUCN red list page, threats to its population numbers are evaluated as least concern; however, their numbers are threatened by habitat loss, climate change, and feral predators.

<i>Ctenophorus parviceps</i> Species of lizard

Ctenophorus parviceps, commonly known as the Gnaraloo heath dragon or northwestern heath dragon is a species of agamid lizard occurring in pale coastal sands and shell grit with open heaths and beach spinifex, between the North West Cape and Carnarvon, Western Australia and on Bernier Island. The Gnaraloo heath dragon is a lizard that can be found along the coast of Western Australia between Exmouth Gulf and Shark Bay, and is also known as the northwestern heath dragon. It is native to Australia and usually inhabits sandy coastal dunes. The species' longevity is 3–50 years and its population density is extremely low. The Gnaraloo heath dragon is a member of the Agamidae family, which contains 15 genera. The lizard is under the Ctenophorus genus which has up to 33 species. This genus shows the most morphological and ecological diversity out of the three large agamid genera. 83% of the lizards in this genus lack a crest, while 17% possess crests. They are smaller than most agamids but do have relatively large heads. The Gnaraloo heath dragon can be differentiated from related species by a series of spines on the tail's base, a pale-grey brown broad vertebral band along its back, and hour-glass bars extending upwards to meet the pale vertebral band. It is usually 45mm in terms of length, measuring from snout to vent.

They are curious creatures and can be found darting between the safety of Triodia grass clumps or basking on the red sand.
