''Bothriechis'' is a genus of venomous pitvipers commonly called palm vipers〔Mehrtens JM. 1987. Living Snakes of the World in Color. New York: Sterling Publishers. 480 pp. ISBN 0-8069-6460-X.〕 or palm-pitvipers〔Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. ISBN 0-8014-4141-2.〕 found predominantly in Mexico and Central America, although the most common species, ''B. schlegelii'', ranges as far south as Colombia and Peru. All members are relatively slender and arboreal. The name ''Bothriechis'' is derived from the Greek words ''bothros'' and ''echis'' that mean "pit" and "viper" respectively.〔 Ten species and no subspecies are currently generally recognized.〔 (【引用サイトリンク】 work = Encyclopedia of Life )〕〔 ==Description== Species that belong to this genus typically reach lengths of 60–80 cm, while ''B. aurifer'', ''B. bicolor'' and ''B. lateralis'' are known to grow to 1 m or more.〔 General characteristics include a sharply defined canthus rostralis, an unelevated snout, a rostral scale that is not as high as it is broad, and a prehensile tail that accounts for at least 15% of the body length.〔 The color pattern usually consists of a green ground color that may or may not include pale or dark markings. ''B. schlegelii'' is an exception to this rule.〔 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「Bothriechis」の詳細全文を読む スポンサード リンク
