A pale green arboreal species that may reach 1 m inlength, it is an important cause of snakebite throughout the entire Amazon region. Two subspecies are currently recognized, including the nominate subspecies described here. ==Description== Adults usually do not grow to more than 70 cm in length, although some may reach 100 cm. The maximum reported size is 123 cm. The body is relatively slender, with a prehensile tail.〔 The scalation includes 23-35 dorsal scales at midbody, 190-218/192-220 ventral scales in males/females and 65-76/55-73 mostly divided subcaudal scales in males/females. On the head are 5-9 keeled intersupraoculars, 8-12 sublabial scales and 7-9 supralabial scales. Of the latter, the second is usually fused with the prelacunal to form a lacunolabial, although partial or complete sutures may exist to separate these scales.〔 The colour pattern consists of a pale green ground colour overlaid dorsally with either a peppering of black spots, or a series of tan or reddish brown spots that are usually paired. The ventrals are bordered by a creamy yellow line running down the length of the body, while the belly itself is yellow and bordered with a tinge of green. The latter part of the tail is pink and bordered with yellow. The head is either green with a scattering of small black spots, or green with isolated tan or reddish brown spots that are bordered in black. The iris is pale green, while the labials are yellow green, often with black spots.〔 The nominate subspecies, ''B. b. bilineata'', has vertical dark stripes on the supralabial scales and a dorsal pattern of reddish brown spots with black flecks.〔 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 bilineata」の詳細全文を読む スポンサード リンク
