Lophognathus is a genus of lizards found in northern Australia extending south to the Murray-Darling Basin, New Guinea, and Tanimbar Islands. The five species, among which the long-nosed water dragon (Amphibolurus longirostris), are informally described as dragons, as are several genera in the family Agamidae, and closely related to those of Amphibolurus.
Lophognathus species are slender, slightly compressed, agamid lizards that are often found in trees. They occur in a variety of habitat, including sand dunes and arid regions, but frequently near watercourses. Three species are endemic to Australia, L. burnsi, L. gilberti and L. longirostris; L. temporalis is found in both Australia and New Guinea. The last species, L. maculilabris, is endemic to the Tanimbar Islands (Timor Laut).
In Australia, these lizards are colloquially known as "Ta Ta" lizards, due to their habit of "waving" after running across hot surfaces.
Amphibolurus, a genus of lizards native to Australia, inhabit
woodlands in temperate and semiarid areas, as well as riverine
vegetation in the tropical areas of Australia. They are partially
arboreal and are often found perching on trunks and branches. Lizards
of this genus are swift and shy, and when disturbed, they can engage
in bipedal running.
