(7th printing, 1985). 1105 pp. ISBN 0-8014-0463-0.〕'' ''Crotalus viridis nuntius'' is a venomous pitviper subspecies native primarily to the desert plateau of the northeastern portion of the American state of Arizona, but also ranges into northwestern New Mexico. Named for the Native American Hopi tribe, which inhabits the region, its range overlaps that of the dominate subspecies and some interbreeding is believed to occur. The taxonomy of the ''C. viridis'' group is a matter of debate, many considering the various subspecies to be nothing more than locality variations. ==Description== Smaller than other subspecies of ''C. viridis'', this subspecies generally does not generally grow much beyond two feet in length. They are typically pink, to gray, to orange-brown in color, reflecting the color of the soil and rocks of their natural range for camouflage, with darker brown blotching down the back. The scalation consists of 21-27 (usually 25) midbody dorsal scales, 169-184 ventral scales in females and 162-178 in males, 14-22 subcaudal scales in females and 21-28 in males. The color pattern includes 33-53 dorsal body blotches. According to Douglas ''et al.'' (2002), it is not possible to reliably distinguish ''C. v. nuntius'' from ''C. v. viridis''.〔 Like other rattlesnakes, they have eyes with vertical pupils, and their tail has a rattle on it. The rattle is composed of keratin. Each time the snake sheds its skin, a new segment is added to the rattle, but the rattle is fragile and may break off, and the frequency of shedding can vary, so the snake's age cannot be determined by its length or number of segments. 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「Crotalus viridis nuntius」の詳細全文を読む スポンサード リンク
