Lophognathus is a genus of large-bodied agamid lizards, consisting of two species — L. gilberti and L. horneri — both of which are endemic to northern Australia. Along with several other closely related genera (e.g., Amphibolurus , Gowidon , and Tropicagama ), these lizards are commonly referred to as "dragons". In Australia, these lizards are also colloquially known as "Ta Ta" lizards, due to their habit of "waving" after running across hot surfaces.

Lophognathus are slender, slightly compressed, semi-arboreal lizards. They occur in a variety of habitats, including sand dunes and arid regions, but frequently near watercourses.

Taxonomy

The genus Lophognathus was originally named and described by John Edward Gray in 1842. [1]

Species

The eastern bearded dragon, also known as common bearded dragon or simply bearded lizard, is an agamid lizard found in wooded parts of Australia. It is one of a group of species known commonly as bearded dragons. Other common names for this species include Jew lizard and frilly lizard, the latter being a confusion between this and another dragon, the frill-necked lizard. This species was originally described in 1829 by Georges Cuvier, who named it Amphibolurus barbatus.

The Amphibolurinae are a subfamily of lizards in the family Agamidae. Members of this subfamily are found in Australia and New Guinea, although one species, the Chinese water dragon, is found in Southeast Asia.

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

Ctenophorus maculosus, commonly known as the Lake Eyre dragon or salt-lake ground-dragon, is a species of agamid lizard endemic to South Australia. C. maculosus mainly inhabits the edges of salt lakes in South Australia, from which its common names are derived. It survives in this harsh habitat through adaptive mechanisms to tolerate high temperatures and lack of free water. The female C. maculosus possesses unique male rejection techniques which are currently the focus of further research.

<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.

<i>Gowidon</i> Genus of lizards

Gowidon is a genus of arboreal lizards in the family Agamidae. It is monotypic with a single recognised species, Gowidon longirostris, commonly known as the long-snouted lashtail or long-nosed water dragon. It is found in Northern Territory, Queensland, South Australia, Western Australia, Australia, and in New Guinea.

This semi-arboreal species inhabits the tropical savannah woodlands of northern Australia, as well as parts of New Guinea and southeastern Indonesia.
