As their name suggests Aru Green Tree Pythons come from the Aru Islands. A group of around 95 low lying islands located in the Arafura Sea southwest of mainland New Guinea and north of Australia. The Aru islands rise from the Sahul Shelf. The Sahul Shelf is part of the continental shelf of Australia that stretches across northern Australian north to New guinea. Currently the Arafura Sea covers the Sahul shelf but during the last glacial maximum roughly 18,000 years ago, Australia, New Guinea, and the Aru Islands were connected by dry land. As a result, the Aru Islands fauna is similar to that of Southern New Guinea and Australia’s Cape York peninsula including the Southern Green Python.

The Green Python python viridis was originally described by Herman Schlegel in 1872 from a specimen collected from the Aru archipelago. The Southern Green Python (morelia vividis) includes animals from the Aru Islands, Australia’s Cape York peninsula, along with specimens found south of the Central dividing range on the Island of New Guinea typically referred to as Merauke in captive collections.

Aru Green Pythons hatch a brilliant yellow color with a larger pattern of purply brown bordered thin white splotches alternating along the spine and smaller spots and dots along the rest of the body with a dark tipped tail. The Yellow body color typically begins to turn green starting around 8-12 months of age and is mostly complete by the age of 18 months. The juvenile pattern elements turn blue and in some areas small clusters of white scales form predominantly along either side of the spine. Adult Aru Green Pythons are typically a very pleasing shade of green with a smattering of blue elements along the spine with white speckles with the tail typically being a mixture of white, green, blue and black in no particular order. The amount of white and intensity of the blue pattern vary widely among specimens. Most Aru animals have a large blue border along their sides that stands in contrast to the white belly and green body. In some individuals, there is also some yellow patches mixed in along with the blue sides. The snout length of the southern species is not as long and pronounced as the northern species and the tail is blunt without the sharp tip found in northern animals.

The Aru specimens are typically known for having a calm disposition and make for incredible animals to keep. “High White” individuals are considered by some to be the most incredible appearance of all the Green Pythons.

Aru Type

By Freek Nuyt

This is an insular form originating from the Aru islands that lie in the Arafura sea off the coast of Indonesia. Typical characteristics are a deep green color with small white scales that can form a complete line on there back, all pure arus have sky blue ventrals and sometimes blue spots scattered randomly over there entire body and a blunt tail. Clutch size has ranged from 14 to 27 eggs, all babys that i hatched have been yellow until now. Some aru’s are sometimes misidentified as merauke animals because of the dorsal white line, this however is not a feature by which the two localities can be identified as both can have a full, partial or absence of the white dorsal line. These animals have a very calm disposition.

This group of chondros represents a natural color variant found on the Aru islands of Indonesia.  It is characterized by the rich blue-green body color and a normally large amount of white flecking.  Aru chondros are also known to display varying amounts of blue, particularly as lateral rosettes and near the ventral scales.

The Aru Type

By Christos Issaris

Aru animals are by far the most peaceful representatives. However, this calm temperament can also lead to problems with the rearing of young animals, since these cannot be aroused in order to catch the food. 

Aru animals have a larger posterior head, which tapers to the nose, the final size exceeds the 150cm and few copies reach the 180cm. Nevertheless, these animals are not as large as the biak forms. Aru-animals have a grass-green coloring. Along the back, the green is concentrated in a darker strip and there are also several white scales. These do not form a continuous line like the Merauke animals. But other white scales can also appear scattered on the rest of the body. Copies with a fattened white line are often sold as Merauke animals. These two forms are very similar to each other. Merauke animals usually carry a white solid line along the back, grass-green color and a yellow belly. There are, however, representatives of this kind who do not have any of these features. Even such animals are often sold as Aru animals.
