In certain species only the male has these pores and in other species, both sexes have them, with the males being larger. Femoral pores appear as a series of pits or holes within a row of scales on the ventral portion of the animal's thigh. Femoral pores are present in all genera in the families Cordylidae, Crotaphytidae, Hoplocercidae, Iguanidae, Phrynosomatidae, and Xantusiidae.〔 They are absent in all genera in the Anguidae, Chamaeleonidae, Dibamidae, Helodermatidae, Scincidae, Xenosauridae, and Varanidae families.〔 They are present in other lizards and amphisbaenians quite variably, some geckoes, ''Phelsuma'', for example have these pores, others in the same family do not.〔 In the desert iguana (''Dipsosaurus dorsalis''), the waxy lipids released from the femoral pores absorb ultraviolet (UV) wavelengths making them visible to species which can detect UV light. According to tests performed on the Green iguana, the variation in the chemicals released by the femoral pores can lead to determine age, sex, and individual identity of the animal in question. Male leopard geckos (''Eublepharis macularius''), actually taste the secretions by flicking their tongues, if a male determines the other gecko in question is a male, the two will fight. In certain species such as geckoes, the females lack femoral pores altogether. In most families of lizards that have femoral pores, notably the iguanids, both sexes have femoral pores, but the males tend to be much larger than females of the same size and age.〔 In these instances they are used as a marker for sexual dimorphism.〔 ==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「Femoral pore」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
