  phrynocephalus is a genus which includes 44 species of small and medium-sized agamid lizards, commonly called toadhead agamas or toad-headed agamas, that inhabit open arid and semiarid environments of asia and eastern europe. the systematics of this genus is very complicated with many controversial points of view about the unclear phylogeny of this group. all representatives of this genus have adopted the so-called "sit and wait" hunting strategy and they actively use visual orientation when watching for food. in general, the ecological niche and role of phrynocephalus species in lizard communities of arid environments of asia are poorly studied, but seem to be similar to that of phrynosoma, cophosaurus, holbrookia, uta, and sceloporus in the new world, as well as moloch in australia. ==speciesphrynocephalus, the reptile database. www.reptile-database.org.== *phrynocephalus albolineatus (zhao, 1979) â white-lined toadhead agama *phrynocephalus alticola j.a. peters, 1984 â montane toad-headed agama *phrynocephalus arabicus (j. anderson, 1894) â arabian toadhead agama *phrynocephalus arcellazzii (bedriaga, 1909) â central asian toadhead agama *phrynocephalus axillaris (blanford, 1875) *phrynocephalus birulai (tzarevsk, 1927) â tsarewsky's toadhead agama *phrynocephalus clarkorum (s.c. anderson & leviton, 1967) - clarks' toad-headed agama *phrynocephalus elegans (tzarevsk, 1927) â elegant toadhead agama *phrynocephalus euptilopus (alcock & finn, 1897) â alcock's toad-headed agama *phrynocephalus forsythii (j. anderson, 1872) â forsyth's toadhead agama *phrynocephalus geckoides (bedriaga, 1909) â gecko toadhead agama *phrynocephalus golubewii (shenbrot & semyonov, 1990) *phrynocephalus guinanensis (ji, wang & wang, 2009) zootaxa *phrynocephalus guttatus (gmelin, 1789) â spotted toadhead agama *phrynocephalus helioscopus (pallas, 1773) â sunwatcher t
