The knob-scaled lizard (''Xenosaurus grandis'') is a diurnal, terrestrial lizard found in Mexico and Guatemala. It primarily inhabits tropical rainforests. It dwells in rock crevices and eats insects. Its name, ''Xenosaurus grandis'', comes from the Greek words ''xenos'', meaning “alien”, “stranger”, or “foreigner”, ''saurus'', meaning “lizard”, and ''grandis'', meaning “grand” or “great”. Its common name of ‘knob-scaled lizard’ derives its name from the bumpy, ‘knob-like’ scales found on the upper portion of its body. 〔Gadow, H. (1901). ''Amphibia and Reptiles.'' Macmillan & Co, London.〕 There are 5 recognized subspecies, which are spread throughout the species’ range, and the species complex is being reevaluated. Some of the subspecies are currently in the process of being elevated to species status. The species as a whole is listed as vulnerable by the IUCN Red List and its population is currently decreasing. ==Physiology== 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「Xenosaurus grandis」の詳細全文を読む スポンサード リンク
