ISBN 0-8014-4141-2.〕'' ''Bothriopsis punctata'' is a venomous pitviper species found in South America and Panama. No subspecies are currently recognized. ==Description== Adults commonly grow to more than 100 cm in length and may exceed 150 cm. The shape of the body and long tail suggest that it is semiarboreal. The head is long and lance-shaped and the fangs exceptionally long.〔 The scalation includes 25-29 rows of dorsal scales, 186-211/191-213 ventral scales in males/females and 70-95/80-90 paired subcaudal scales in males/females. The tail ends in a long rounded spine that may turn upwards slightly at the tip. On the head there are 6-9 intersupraocular scales, 7-9 supralabial scales, the second of which contacts the prelacunal, and 11-12 sublabial scales.〔 The color pattern consists of a pale brown to greenish tan ground color overlaid with 16-22 pairs of darker brown paravertabral blotches that have pale edges. Some of these blotches coalesce dorsally. These blotches are offset by a row of lateral blotches that create a semibanded appearance. Below this is a third series of dark blotches, alternated with lighter spots, that extends down onto the ventral scales. The belly is cream to pale tan with brown spots. A dark brown cheek stripe is present that is darkest along the outer edges where it is narrowly bordered by a lighter color that can sometimes be orange or yellow.〔 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「Bothriopsis punctata」の詳細全文を読む スポンサード リンク
