Species description
Geographical Origin and Habitat: This fascinating subspecies is native primarily to the southern regions of New Guinea (both the Indonesian part of Irian Jaya and Papua New Guinea). It lives in a variety of habitats ranging from dense tropical rainforests to open eucalyptus woodlands and wooded savannas, showing excellent adaptability and marked arboreal habits.
Taxonomy and Genetics: Belongs to the family Boidae, subfamily Pythoninae, species Morelia spilota. The subspecies Morelia spilota harrisoni represents the only carpet python population living outside of Australian territory. Genetically stable, it is highly valued in herpetoculture and has been bred to select specific color morphs such as 'Granite' or 'Jaguar'.
Behavior and Habits: Semi-arboreal snake with an active temperament. Juveniles are known to be rather defensive, territorial, and prone to delivering defensive bites ('nippy' behavior) when handled. With growth and regular, respectful handling, adults calm down significantly, becoming curious, docile, and easily manageable animals.
Morphology: It is one of the smallest carpet python subspecies, with males reaching an average of 140-160 centimeters and females 180-200 centimeters. It features a slender but muscular body, a head well-distinct from the neck, and prominent heat-sensitive pits. Colors range from caramel brown to cream with black geometric patterns.
Care, breeding and tankmates
Terrarium Setup: Requires a vertically oriented terrarium due to its arboreal habits. The minimum dimensions for an adult specimen are 120x60x100h centimeters. It is indispensable to insert numerous robust branches arranged at various heights, suspended platforms, artificial plants for cover, and at least two dry hideouts.
Lighting and Heating: Needs a daily thermal gradient. The warm zone must reach a temperature of 31-33 °C using a ceramic heating lamp or spot bulb (shielded by an anti-scald protective cage), while the cool zone should settle at 24-26 °C. At night, the temperature can drop to 22-24 °C. The use of 5% UVB lamps is highly recommended.
Humidity and Hydration: Relative humidity should be maintained between 50% and 70%. This is achieved by lightly misting the terrarium every other day and providing a large water bowl on the bottom that allows the snake to submerge completely during shedding. The water must always be fresh and clean.
Feeding and Supplementation: Extremely voracious feeders with a very strong feeding response. They feed on thawed mice or rats of size appropriate to their weight, offered with long tongs to avoid accidental bites. Juveniles should be fed every 7-10 days, adults every 14-21 days. No supplementation is needed if the diet is whole prey.
Compatibility: Strictly solitary snake, must be housed individually. Cohabitation of multiple specimens in the same terrarium causes high stress and can lead to cannibalism or serious injury. During cleaning or feeding operations, the use of a snake hook is recommended to manage the animal safely.
Health and Common Diseases: It is a robust and long-lived subspecies. The most common pathologies are related to poor management of thermal and humidity parameters, such as respiratory infections (pneumonia), dysecdysis (incomplete shed), and dermatitis from overly wet substrate. Beware of burns from unshielded heat lamps.
