Green tree pythons are strikingly beautiful, distinctive reptiles. They have a reputation for their feisty attitudes, but they make beautiful and unique pets. Green tree pythons color morphs and patterns vary, depending on which area (locality) they’re from.
We’ll be looking at the most popular green tree python localities. We’ll discuss where they come from, what they look like and how much they cost. We’ll also discuss the beautiful yet rare “designer” green tree pythons which breeders have created by selective breeding.

What Are Green Tree Pythons?
Green tree pythons, scientific name Morelia viridis, are a type of arboreal (tree-dwelling) python. They have slim bodies, long tails, and large, muscular heads.
Like all pythons, green tree pythons are non-venomous, and constrict their prey. They spend most of their time sedentary, wrapped around tree branches, waiting for prey to cross their paths.
You may have heard green tree pythons referred to as “chondros.” This is a nickname stemming from their original taxonomic name, which used to be Chondropython viridis.
As their name suggests, they are mostly green in color. Most individuals have a vivid, grass-green body, though it may be lighter or darker. Their dorsal color may be interspersed with markings of white, yellow, black or blue.
Chondros are native to New Guinea, Indonesia, and extreme northern Australia. Like most snakes, the appearance of a green tree python varies slightly depending on where it comes from. When we refer to a green tree python “morph,” we’re referring to their locality.
Technically, it’s incorrect to refer to localities as “morphs,” as they occur naturally – they aren’t a result of selective breeding. However, they are often colloquially called morphs.
Some breeders have begun to delve into the world of “designer” green tree pythons, but they’re still quite rare.
Green Tree Python Ontogenetic Color Change
All green tree pythons are green – at least partially. However, you may have seen photos of bright yellow or red-green tree pythons. Your eyes aren’t deceiving you – these are just juveniles.
Baby green tree pythons can be yellow, orange or brick red. They have white or yellowish spots along their backs, outlined in brown.
Between 6 and 24 months, they go through a process called ontogenetic color change. This transforms their scales into the classic green. Red babies turn orange and then yellow before going green, so their transition can take longer.
According to Biology Letters, this color change helps to camouflage them. Adult green tree pythons spend more time in the forest canopy, amongst green leaves. Babies, on the other hand, spend more time at the edge of the forest.
When buying a green tree python morph, be aware of this color change. If the snake is less than three years old, it may still change in appearance drastically.
A Guide to Green Tree Python Morphs (Localities)
The localities you can find for sale in this country are all from Indonesia (or have been captive-bred in the U.S. from Indonesian heritage).
Though some green tree pythons are from Australia and Papua New Guinea, we haven’t included them in this guide. It’s illegal to export green tree pythons from these countries, so you can’t buy them in America.
|Locality||Appearance (adult, 2+ years)||Price Range|
|Biak:||Green body with asymmetrical patches of yellow. The shade of green can vary greatly.||$275 – $350|
|Aru:||Vibrant green body color with blue blotches. Random white scales which may appear in clusters. Some specimens have a blue line bordering the belly.||$400 – $450|
|Jayapura:||Blue-green body color with blue striping along the back. Some yellow or white scales. Black-tipped tail.||$350 – $475|
|Sorong:||Light to medium green body. Blue dorsal line and blue triangles either side of the line. Black-tipped tail.||$350 – $500|
|Manokwari:||Light green body. Bright blue dorsal markings which vary in size. Some single white scales. Black and blue tail.||$350 – $450|
|Wamena:||Deep green body color with darker green or yellow dorsal markings, sometimes surrounded in blue. Some Wamena pythons have patches of black pigmentation.||$400 – $500|
Let’s now discuss each type of green tree python in more detail.
For each locality, we’ll take an in-depth look at their appearance and price range. We’ll also share some facts about the area they’re from, and how easily you can find them for sale.
Biak Green Tree Pythons
Biak green tree pythons are the most common type that you’ll see for sale in the U.S. They are from eastern Indonesia, specifically the island of Biak. It’s located near the northern coast of the province of Papua.
Snakes from the Biak region (or descended from Biak pythons) are the largest of all green tree pythons. They can reach lengths of 6 feet, if cared for well enough. Their heads also have an elongated appearance.
The “attitude” of biak chondros is well known. They tend to be the most feisty and defensive of all green tree python localities. That being said, many biak owners claim that they can be tamed with persistence.
Biak chondro babies can be either red or yellow. It can take up to 5 years to grow out of their baby colors. Adults can range from pale green to vivid green, and often retain a lot of yellow coloration into adulthood, in the form of asymmetrical splotches.
As Biaks are the most common, they tend to be the cheapest. Babies can range between $275 and $350. Adults are more expensive, as is the case for all chondros.
Aru Green Tree Pythons
After Biaks, Arus is the next most well-known green tree python variation. They hail from the Aru Islands, which are in southeastern Indonesia. The population of green tree pythons on the Aru islands is the most isolated of all localities, and Arus are quite sought-after.
Arus have relatively short and blunt tails compared to all other green tree pythons, and their heads are short and bulky. Neonates are always yellow. As adults, they transform into a stunning and vivid emerald green.
They have flecks of pale blue throughout their bodies, and often a blue line bordering the belly scales. They also have many clusters of large white scales (or small clusters of scales) down their spines.
Aru green tree pythons are more expensive than Biaks, at $400 – $450 each.
Jayapura Green Tree Pythons
Jayapura green tree pythons are found in the region of Jayapura, the capital city of the province of Papua. It is located on the northern border of New Guinea, in mainland Indonesia.
Rather than the city itself, Jayapura pythons come from the mountain ranges surrounding the area. The neighboring regions of Lereh, Arso, and Cyclops Mountain are also home to similar strains, though they aren’t as popular as Jayapuras.
Jayapura neonates can be either red or yellow. Generally, red babies grow up to be darker green than yellow babies. Their primary color can range from pale olive green to bluish-green.
They have a solid blue dorsal stripe down their spine, with blue markings on either side. Jayapuras often have sparsely dotted white scales. They can also have some black scales (melanism), though this is rarer.
Jayapuras are one of the smaller types of green tree python. They’re also less defensive around humans than Biaks and Arus, making them a good beginner chondro. Baby Jayapuras can range from $350 to $475 each.
Sorong Green Tree Pythons
The Bird’s Head Peninsula of northwest New Guinea is home to the Sorong green tree python. Sorong is the largest city in West Papua, on the northeastern coast of the Bird’s Head Peninsula.
Though orange Sorong also exists, they’re quite rare. The vast majority of neonates from this locality are bright yellow. The babies typically have very dark brown dorsal stripes, which turn blue as adults.
Adult Sorongs are green tend to be lighter than most other localities. They’re closer to lime green than the vivid grass-green often seen in chondros.
They have a thin, unbroken blue dorsal stripe with blue triangle-shapes on either side. Typically, Sorongs have very few white or yellow scales, if any. Their tails are long and pointed, with black tips.
Baby Sorong green tree pythons typically sell for $350 – $500. The older they are, the more they’ll cost, as their adult colors begin to show themselves.
Manokwari Green Tree Pythons
Manokwari green tree pythons also come from the Bird’s Head Peninsula, like Sorongs. Manokwari is the name of a town on the northeastern coast of the peninsula. It’s also the capital of the province of West Papua.
Because they’re so close to Sorong, Manokwari green tree pythons typically look quite similar. They’re light green in color, with a blue dorsal stripe and blue patches.
However, their blue coloration tends to be much more vivid than Sorong pythons. The stripe tends to be thicker, too. They also often have randomly dotted white scales, whereas Sorongs don’t usually have any. Their tails are blue, darkening to black at the tip.
Manokwari chondros sell for $350 – $450 each as juveniles.
Wamena Green Tree Pythons
Wamena is the name of the capital town of the Jayawijaya Regency, in central Papua. It’s a very urban area, so the name “Wamena green tree python” is a bit of a misnomer. There aren’t any green tree pythons from the Wamena region.
However, Wamena has a busy airport. When green tree pythons are collected from the surrounding mountain ranges, they’re exported from Wamena airport, and given the name Wamena.
As Wamena pythons can be from many different areas, their appearance can vary. They are usually a deep emerald green, sometimes with a blue undertone. They can have yellow or dark green patches, sometimes outlined in blue. Some Wamena chondros can have patches of black, too. Babies can be yellow or red.
Wamena pythons usually sell for $400 -$500 each.
Green Tree Python Color Morphs and Crossbreeds
Green tree pythons can be challenging to look after – see our in-depth green tree python care guide for beginners. Though they have been gaining a larger following in recent years, they aren’t as popular as other pet snakes (such as corn snakes or ball pythons).
For this reason, green tree python morphs – that is, pythons that look a certain way due to selective breeding – aren’t widely available yet.
Some breeders have begun to experiment with “designer” chondros. As yet, though, their snakes are very expensive and of limited availability. When they are for sale, they cost thousands of dollars.
They create various looks by cross-breeding different localities together, selecting the snakes that express certain traits.
Mite Phase Green Tree Pythons
Mite phase green tree pythons have speckles and clusters of black scales on their bodies. The dotted black scales are reminiscent of mites. Fortunately, they are not infested.
Sometimes, you might see mite phase chondros referred to as “melanistic.” This is in reference to melanin, the black pigment which mite phase chondros have more of.
Most mite phase green tree pythons lose a lot of their black scales as they age.
High Blue Green Tree Pythons
High blue-green tree pythons are created from breeding snakes with a lot of natural blue pigmentation (usually Jayapura specimens). They have blue bodies, ranging from teal to cornflower blue. They usually still retain some patches of green.
Many online images of “blue” green tree pythons are edited, to make the color appear stronger. Be very careful when making a purchase – always meet the snake in person, if you can.
High Yellow Green Tree Pythons
Similar to high blue, high yellow-green tree pythons are bred from snakes that have a lot of yellow pigment. They’re usually bred from biaks, as these specimens usually contain the most yellow.
High yellow-green tree pythons still have many green scales. The amount will vary from snake to snake.
Albino Green Tree Pythons
Albinism is a genetic defect that reduces or eradicates the production of melanin. Albinism in green tree pythons is rare. Only a tiny number of albino green tree pythons have been confirmed.
They are beautiful, though – a deep golden yellow in color, with yellow eyes, and some scattered white scales. They’re the only type of green tree python that doesn’t feature any green. As they’re so rare, they aren’t yet available for sale.
