Beautiful Sumatran female, from an island near the eastern coast of northern Sumatra.
Juvenile male in the terrarium of Ewald Toenjes.
Large adult female, about 80-90 cm, gravid (April), from a location southwest of Medan, North Sumatra. Other adult females from this location looked similar, blueish-white against strongly yellow bars. However, there were also females with mostly green scales, very similar to specimens from Thailand or western Malaysia.
Adult female, about 70 cm, from the same population as the female above, displaying more greenish coloration.
Adult male, (about 50-60 cm), from the same location as the two females above. As mentioned elsewhere on this site, this male displays the characteristic green coloration (including the ventral scales) frequently encountered in Sumatra. This is less frequent with regard to males from western Malaysia and Thailand. This male was captured in a sugar palm tree (Arenga pinnata), several meters above the ground. Potential prey is abundant in these trees like geckos, birds and squirrels.
Adult male, about 50-60 cm, from the same population as the animals above. It was found in a guava tree in the late afternoon, about 3 m above ground, behind a farmers house. Note the blueish-white belly and the relatively smaller red dorsal marks, well in contrast to the male above. This pattern is very similar to Thai and western Malaysian males.
Adult female, about 50 cm, from the vicinity of Medan. This beautiful specimen features more dark elements of coloration on the back.
Subadult female from the vicinity of Medan. This specimen was probably entirely green during the juvenile phase, as opposed to blueish juvenile females that also occur in the same area.
Same animal as above, after shedding skin about 3 months later. Incredibly fast and beautiful change!
Sumatran subadult female, approximately 2-3 years old, in transition to adulthood; locality unknown.
