New York: Sterling Publishers. 480 pp. ISBN 0-8069-6460-X.〕'' ''Lachesis stenophrys'' is a venomous pitviper species endemic to Central America. The specific name, ''stenophrys'', is derived from the Greek words ''stenos'', meaning "narrow", and ''ophrys'', meaning "brow" or "eyebrow".〔Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. ISBN 0-8014-4141-2.〕 No subspecies are currently recognized.〔 ==Description== Adults commonly grow to more than 200 cm (6 feet 6¾ inches) and may exceed 330 cm (10 feet 10 inches) in total length. Ditmars (1910) reported a specimen from Costa Rica that was 11 feet 4 inches (349 cm). Many accounts exist of much larger specimens, but these are poorly documented. Solórzano (2004) cites historical records that put the maximum length at 360 cm (11 feet 9¾ inches). It has a broadly rounded head and a snout that is not elevated. Typically, the species has a pronounced middorsal ridge that is most distinct on the last quarter of the body.〔 The color pattern is darker than that of ''L. muta''.〔 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「Lachesis stenophrys」の詳細全文を読む スポンサード リンク
