Prehensile-tailed giant skink — Care Sheet & Morphs

Husbandry requirements

Prehensile-tailed giant skink — origin: Solomon Islands archipelago (Melanesia); humid lowland and mid-altitude tropical forests, arboreal lifestyle..

Terrarium temperature gradient

Night min20 °C

Cool side24–26 °C

Warm side28–30 °C

Crepuscular/nocturnal forest species: NO intense heliophilic basking spot. A slight thermal gradient is sufficient. Any temperature above ~32 °C is dangerous, even lethal (risk of hyperthermia). A night-time drop (20-22 °C) is beneficial.

Enclosure (adult)

120 × 60 × 120 cm

Vertical arboreal terrarium, planted (bioactive recommended)

Vertical volume is the priority: solid, diagonal branches are essential (prehensile tail), with elevated hides and dense foliage. Dimensions given for one adult or a pair; a group (circulus) requires considerably more space. Introducing new individuals is tricky due to territorial aggression.

Humidity

60–80 %

High and stable humidity, but good ventilation is imperative to avoid stagnant air and respiratory infections. Daily misting, heavier in the evening.

Substrate

Coco fibrePotting soil + sphagnumOrchid barkLeaf litter

Substrate that retains moisture with a drainage layer. A planted bioactive terrarium (pothos/Epipremnum, ficus, philodendron) serves at once as food, as a climbing support and to regulate humidity.

UVB

Recommended

Crepuscular species: a low UVB remains beneficial for a folivore (T5 tube at 5-6%, UV index ~1-2, at a good distance), with mandatory dense shade zones. Avoid high intensities.

Water source

Always available

A small container of clean water renewed daily, supplemented by regular misting: the animal often drinks the droplets deposited on the foliage.

Origin

Scincidae

Solomon Islands archipelago (Melanesia); humid lowland and mid-altitude tropical forests, arboreal lifestyle.

Feeding & health

Diet

Herbivore (strict folivore) — None (strict vegetarian, unlike most skinks)

Foliage-based: pothos (Epipremnum) is a well-tolerated staple, supplemented with hibiscus, ficus, mulberry, dandelion, turnip/collard greens and various leafy greens. Fruit in limited quantity (sugar). Regular calcium (+ D3) supplementation. Important: neonates ingest the adults' faeces (coprophagy) to acquire the gut flora needed to digest plant matter.

Breeding

Viviparous

Exceptionally long gestation (6-9 months). Generally 1 to 2 huge neonates, reaching about 1/3 of the mother's size at birth. Marked parental care and group (circulus) protection; sexual maturity around 3-4 years. Demanding to breed in captivity.

Health watch points

Internal parasites (nematodes, coccidia), very common in wild-caught animals — quarantine and faecal examination essential
Metabolic bone disease (MBD) from calcium / vitamin D3 deficiency
Stomatitis and mouth infections
Dystocia (retention of the young) linked to the very long gestation
Respiratory infections favoured by stagnant humidity and insufficient ventilation

Frequently asked questions

Answers to the most common questions about keeping the prehensile-tailed giant skink.

How big can an adult Solomon Islands giant skink grow?▾

Corucia zebrata is an impressive animal: an adult measures 60 to 80 cm from head to tail tip, making it the heaviest skink species in the world, with a weight that can approach 700 to 800 g. Its fully prehensile tail acts as a genuine fifth limb for climbing and gripping branches.

What kind of terrarium does this arboreal species need?▾

Vertical volume matters far more than floor space: allow at least 120 cm in length, 60 cm in width and 120 cm in height for an adult or a pair. Install solid, diagonally angled branches, essential for the prehensile tail, along with dense foliage providing elevated hiding spots; a bioactive, planted setup is strongly recommended.

Does this skink need a powerful basking spot?▾

No, and it should actually be avoided: this crepuscular and nocturnal forest species is not heliophilic. A gentle gradient is enough, with a warm side between 28 and 30°C, a cool side between 24 and 26°C, and a nighttime drop around 20°C. Above 32°C, the risk of hyperthermia becomes real, even fatal.

What humidity level and substrate suit this species?▾

Aim for high, stable humidity between 60 and 80%, with daily misting stepped up in the evening, while ensuring good ventilation so that stagnant air doesn't encourage respiratory infections. The ideal substrate combines coco fibre, potting soil and sphagnum, orchid bark or leaf litter, at once moist and well-draining.

What does a Solomon Islands giant skink eat?▾

Unlike most skinks, this species is strictly vegetarian: pothos (Epipremnum) forms the basis of its diet, supplemented with hibiscus, ficus, mulberry, dandelion, turnip or collard greens and various leafy vegetables, with fruit in limited quantities. Regular calcium and vitamin D3 supplementation is essential.

Is it true that the young eat the adults' droppings?▾

Yes, and this coprophagic behaviour is normal, even essential: newborns ingest the adults' faeces to acquire the gut flora needed to digest plant matter. There's no need to worry about it, nor to clean the terrarium of a family group with young too frantically.

How does this animal get its water day to day?▾

A small container of clean water, refreshed daily, should always be available, but the animal mainly drinks the droplets left on the foliage after misting. Regularly watering the terrarium is therefore at least as important as having a water dish.

How long does a Solomon Islands skink live, and what commitment does that represent?▾

This is a very long-term commitment: longevity commonly reaches 20 to 30 years under well-managed captive care. Before acquiring one, you should therefore think of this reptile as a companion for several decades.

Is this skink easy to handle and suitable for a beginner?▾

No, the species is classed as advanced difficulty and is not suitable as a first reptile. It is territorial towards unfamiliar conspecifics and capable of powerful, painful bites, even though it can form a strong bond with its regular keepers and live in family groups called 'circulus'.

Why is it important to check the animal's origin before buying?▾

Corucia zebrata is listed on CITES Appendix II (Annex B in the European Union): its trade is strictly regulated, and wild populations are declining. Many specimens available on the market are stressed, heavily parasitised wild-caught animals, which absolutely must be quarantined with a faecal examination before any contact with other animals.

How does reproduction work in this species?▾

It is viviparous, with an exceptionally long gestation of 6 to 9 months for only 1 to 2 young, but these are born already huge, reaching about a third of their mother's size. Parental care is pronounced, and sexual maturity is only reached around 3 to 4 years, which makes captive breeding demanding.

What health problems should be monitored in this species?▾

Internal parasites (nematodes, coccidia) are very common, especially in wild-caught animals, hence the importance of a thorough quarantine. Also watch for metabolic bone disease linked to a calcium or vitamin D3 deficiency, stomatitis, respiratory infections favoured by stagnant humidity, and dystocia, which is possible given the very long gestation.
