The rock monitor (''Varanus albigularis''), also called the ''legavaan'' or white-throated monitor, is a species of monitor lizard found in Central, East and southern Africa. It is the second-longest lizard found on the continent, and the heaviest bodied. ==Taxonomy== First described by François Marie Daudin in 1802,〔 these lizards were previously classified as a subspecies of ''Varanus exanthematicus'',〔Laurent,R.F. 1964. ''A new subspecies of Varanus exanthematicus'' (Sauria, Varanidae). Breviora 199: 1–5〕 but have since been declared a distinct species based upon differences in hemipenal morphology.〔Bohme, W. (1991). ''New finding on the hemipenal morphology of monitor lizards and their systematic implications''. Mertensiella, 2, 42–49.〕 The generic name ''Varanus'' is derived from the Arabic word ''waral'' ورل, which is translated to English as "monitor". Their specific name comes from a compound of two Latin words: ''albus'' meaning "white" and ''gula'' meaning "throat". The subspecies of ''V. albigularis'' are: *White-throated monitor, ''V. a. albigularis'' *Angolan white-throated monitor, ''V. a. angolensis'' *Eastern white-throated monitor, ''V. a. microstictus'' *Black-throated monitor, ''V. a. ionidesi''〔http://reptile-database.reptarium.cz/species?genus=Varanus&species=albigularis〕 (but may be synonymous with ''V. a. microstictus'') 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「rock monitor」の詳細全文を読む スポンサード リンク
