Extract from wikipedia:
“Adults average 90-120 cm (3-4 feet) in length, with a maximum grow (although rare) to about 8 feet. The supralabial scales have thermoreceptive pits.²

Completely arboreal with a striking green color in adults. The color pattern on this species can vary from locality to locality. The Aru locality for example is a vivid green with a broken vertebral stripe of white or dull yellow scales. Spots of the same color, or blue spots, may be scattered over the body (Blue spotting commonly was previously the juvenile pattern). Cyanomorphs (blue morphs) are also known to occur but are not considered common at this time.² Juveniles are polymorphic, occurring in reddish, bright yellow and orange morphs."
