Ontogenetic Color Change
One of the most intriguing aspects of the Green Tree Python is its ontogenetic color change. This process typically begins between six months to a year of age and results in the snake’s iconic green coloration (Animal Diversity Web). It is essential to note that this color transformation does not coincide with sexual maturity, which occurs later.
Here’s a timeline for the ontogenetic color change:
| Age (Months) | Color Transition |
|---|---|
| 0-6 | Juveniles are red, yellow, or brown. |
| 6-12 | Gradual change to green coloration. |
| 12+ | Adults exhibit brilliant green, sometimes with blue accents. |
The green coloration provides excellent camouflage among the foliage, aiding in predation and predator avoidance. For a deep dive into their habitat and hunting tactics, visit our article on green tree python habitat and hunting.

Green Tree Python Behavior
Predator Avoidance Tactics
Green tree pythons (Morelia viridis) have developed several strategies to evade predation. Their primary predators include rufous owls, black butcherbirds, diurnal raptors, mangrove monitors, dingoes, and New Guinea quolls (Animal Diversity Web). To protect themselves, these snakes rely heavily on their cryptic coloration. The striking green hue of the green tree python aids in camouflage among the forest canopy, blending seamlessly with the leaves and branches. Additionally, they adopt hiding behaviors, often remaining motionless to avoid detection by predators.
| Predator | Type |
|---|---|
| Rufous Owl | Bird |
| Black Butcherbird | Bird |
| Diurnal Raptors | Bird of Prey |
| Mangrove Monitor | Lizard |
| Dingo | Mammal |
| New Guinea Quoll | Mammal |
Activity Differences Between Genders
Activity levels between male and female green tree pythons differ significantly. Generally solitary animals, the patterns of movement and behavior differ notably between the sexes. Females tend to be more active, frequently changing positions throughout their habitat (Animal Diversity Web). This activity is crucial, particularly during the brooding period, as females need to maintain optimal temperature by repositioning themselves around their eggs.
Males, on the other hand, exhibit a noticeable change in behavior during the mating season. They stop feeding and become more focused on locating potential mates. Unlike some other snake species, green tree python males do not engage in physical combat with other males for mate competition. Instead, their primary energy is dedicated to mate-searching activities.
Maternal Care Behaviors
Among the green tree pythons, maternal care is observed primarily during the egg incubation period. Female green tree pythons are known for their brooding behavior, where they coil around their clutches of eggs. This behavior is crucial for creating a stable and warm environment for the eggs to develop.
During brooding, females may shiver and contract their muscles to generate metabolic heat, ensuring the eggs remain at an ideal temperature. This muscular activity can significantly impact the hatching success and overall health of the offspring. However, once the young hatch, there is no further parental care, and the juveniles are left to fend for themselves.

Green Tree Python Habitat and Hunting
Understanding the environment and hunting behavior of the green tree python is essential to grasp the broader picture of their lifestyle and behavioral nuances, such as yawning.
Arboreal Habitat
The green tree python (Morelia viridis) is highly arboreal. This species is predominantly found in the rainforests of New Guinea, eastern Indonesia, and the northern parts of Australia. Their arboreal nature means they spend the majority of their time in trees, camouflaging themselves within the dense foliage. This habitat provides them with numerous perching sites and vantage points to watch for prey and avoid predators.
In an enclosure, it’s crucial to replicate this habitat by providing vertical space and plenty of branches for climbing. For more information on appropriate setups, check out our guide on green tree python enclosure.
Nocturnal Behavior
Green tree pythons are primarily nocturnal hunters, meaning they are most active at night. This nocturnal activity aligns with the behavior of many of their prey species, which are also active during nighttime. Before undergoing their ontogenetic color change, the juveniles are diurnal, being active during the day (Animal Diversity Web).
Being nocturnal helps these pythons avoid the peak activity times of many predators. During daylight hours, they typically rest coiled among the branches, a behavior that also aids in thermoregulation. For more nuances on their activity patterns, explore our piece on green tree python species.
Feeding Habits
The feeding habits of green tree pythons are influenced by their arboreal and nocturnal lifestyle. They are sit-and-wait predators, meaning they often remain in one spot, waiting for prey to come within striking distance. Their diet primarily consists of small mammals, birds, and occasionally reptiles. As nocturnal animals, their night-time hunting strategy allows them to capture larger nocturnal prey.
Younger pythons, before their ontogenetic color change, focus on smaller prey, such as insects or small amphibians during the day. As they grow and become nocturnal, their prey size increases. If you’re looking to keep one as a pet, you should familiarize yourself with their feeding requirements, which are covered in our green tree python care article.
Here’s a quick overview of their typical prey:
| Age | Typical Prey |
|---|---|
| Juvenile | Insects, small amphibians |
| Adult | Small mammals, birds, reptiles |
Understanding these facets of the green tree python’s habitat and hunting behaviors not only ensures their appropriate care in captivity but also provides insights into their intriguing behavior, including their yawning and how it might relate to their overall physical and behavioral state.

Green Tree Python Anatomy
Jaw Structure
Green tree pythons possess a specialized jaw structure that allows them to consume prey whole. Their lower jaw consists of two separate halves that can move independently, which aids in the ingestion of large prey. These jaws are lined with teeth that point back towards the throat. Additionally, green tree pythons have two extra bone “levers” called quadrate bones, situated between the lower jaws and the skull, enabling significant mouth expansion.
One fascinating behavior associated with their jaw structure is yawning. Snakes like the green tree python yawn to loosen the ligaments that hold their jaw bones to the skull. This behavior also exercises the muscles operating those bones and the rows of movable recurved teeth in their upper jaws. This adaptation is necessary because their anatomy allows them to crawl over their prey to swallow it whole.
| Anatomy Feature | Description |
|---|---|
| Lower Jaw | Two separate, independently moving halves |
| Quadrate Bones | Extra bones enabling jaw expansion |
| Teeth | Four rows of recurved teeth in upper jaw |

Ontogenetic Physical Changes
Green tree pythons undergo significant ontogenetic changes as they mature. One of the most notable changes is their color transformation. Juvenile green tree pythons start with a yellow or red coloration and typically transition to their characteristic green color between six months and a year of age. This ontogenetic color change does not coincide with sexual maturity, which occurs later (Animal Diversity Web).
| Age Range | Color |
|---|---|
| Hatchling | Yellow or Red |
| 6 Months to 1 Year | Green |

Regulatory Adaptations
The anatomical features of green tree pythons also play a crucial role in their regulatory adaptations. One such adaptation involves the frequent yawning observed in these snakes. This behavior helps to loosen the ligaments holding their jaw bones to the skull, allowing flexibility needed to swallow large prey. This loose construction of the jaw is essential, as it enables the snake to maneuver its body over its prey for ingestion (Quora).
The regulation of their body temperature is another critical adaptation for survival. Green tree pythons need a carefully controlled environment to thrive.
