It is usually between 5.5 – 7.75 in (12 – 19.9 cm) long and is slender with many small silvery-blue spots on its back and sides. It is brownish grey and the area around its vent is grey. The silvery salamander a unisexual ''Ambystoma'' hybrid species, taking genetic material from both the Jefferson salamander (''A. jeffersonianum'') and the blue-spotted salamander (''A. laterale''), having two sets of chromosomes from the Jefferson salamander and one set from the blue-spotted. A similar unisexual Ambystomid, Tremblay's Salamander (''Ambystoma tremblayi'' or JLL), also exists, having two sets from the blue-spotted and one from the Jefferson's. While formally named, the silvery salamander is most often referred to by its genomic components (JJL) rather than as ''Ambystoma platineum'' in scientific literature. == Behaviour == Lacking its own males, the Silvery Salamander breeds with male Blue-Spotted or Jefferson Salamanders from March to April. The males' spermatophores only stimulate egg development; their genetic material does not contribute to the offspring's DNA. This mode of reproduction is called kleptogenesis.〔(Unisexual Salamander Complexes )〕 The females lay cylindrical egg masses and attach them to underwater twigs. It is not often observed and its diet and lifestyle are unknown. 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「Silvery salamander」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.
