:''Common names: side-striped palm-pit viper side-striped palm viper,〔(Bothriechis lateralis ) at (Herps of Panama ). Accessed 27 November 2006.〕 more.'' ''Bothriechis lateralis'' is a venomous pit viper species found in the mountains of Costa Rica and western Panama.〔 No subspecies are currently recognized. ==Description== Adult specimens may exceed , but are usually less than in length. These are relatively slender snakes and have a prehensile tail.〔 The color pattern consists of an emerald green to bluish green ground color, overlaid with a series of yellow alternating paravertebral vertical bars. Some of the scales adjacent to the yellow in this pattern may be blue or black-tipped. The belly is a uniform yellowing-green, bordered on either side by a pale yellow stripe running along the lower portion of the paraventral scales and the extreme lateral part of the ventral scales. The head is uniformly green on top and a blue or blue-gray postocular stripe may be present. If a postocular stripe is present, it is weakly defined, especially in large adults. The iris is yellow.〔〔Mehrtens JM. 1987. Living Snakes of the World in Color. New York: Sterling Publishers. 480 pp. ISBN 0-8069-6460-X.〕 Juvenile specimens are usually brown with dark brown markings on the head, bronze irises, postocular stripes, paravertebral makings that are edged with yellow, and a tail tip that is yellow or chartreuse. Captive juveniles retain this color pattern for about six months, after which the ground color starts to become a dull lime green and the yellow edges of the paravertebral vertical bars more prominent. It is thought that the shift to adult coloration takes about 18–24 months to complete.〔 Like many green snakes, captive adults tend to become blue over time, although blue specimens are sometimes found in the wild.〔 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 lateralis」の詳細全文を読む スポンサード リンク
