The common agama, red-headed rock agama, or rainbow agama (''Agama agama'') is a species of lizard from the Agamidae family found in most of sub-Saharan Africa. ==Description== Its size varies from in total length.〔Burton, Maurice and Robert Burton. (2002). ''International Wildlife Encyclopedia'', 3rd edition. New York: Marshall Cavendish Corp. p.30.〕 It can often be seen in the heat of the day. In the breeding season, the males develop dramatically colorful markings, the head and neck and tail turning bright orange, and the body dark blue. Outside of the breeding season, the male is a plain brown. The females and juveniles are always more cryptically marked. This lizard can be found climbing rocks and walls. Its primary source of food is insects. The males are territorial, claiming small to medium-sized patches of land which they defend against other mature males. Juveniles and females reside within the territories unchallenged. The mature males become agitated when confronting each other, nodding vigorously, arching, skipping sideways, and clashing tails. The loser is chased out of the territory. During mating season, males do "push-ups" to attract females. The species name was formerly applied to a paraphyletic collection of taxa, and mitochondrial DNA analysis of various populations indicates they represent separate species.〔Leaché, A.D. et al. (2009). (Phylogeny of the genus ''Agama'' based on mitochondrial DNA sequence data. ) ''Bonner zoologische Beiträge'' 56(4) 273-78.〕〔Mediannikov, O., Trape, S. and Trape, J-F. (2012). A Molecular Study of the Genus ''Agama'' (Squamata: Agamidae) in West Africa, with Description of Two New Species and a Review of the Taxonomy, Geographic Distribution, and Ecology of Currently Recognized Species. ''Russian Journal of Herpetology'' 19(2).〕 Consequently, three former subspecies ''A. a. africana'', ''A. a. boensis'', and ''A. a. mucosoensis'' are now considered separate species, and ''A. a. savattieri'' is considered synonymous with ''A. africana''.〔(''Agama'' ), The Reptile Database〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agama agama」の詳細全文を読む スポンサード リンク
