Diet & Feeding

Green Tree Python Feeding

Morelia viridis

Patient arboreal hunters

Green tree pythons inhabit the rainforests of New Guinea, eastern Indonesia, and the Cape York Peninsula of Australia. They are almost exclusively arboreal โ€” living, hunting, and resting in the forest canopy, where their distinctive coiled posture across a horizontal branch is one of the most iconic poses in the snake world.

GTPs hunt by ambush, dangling the tip of their tail as a lure to attract small prey. The tail of juveniles is often a contrasting yellow or white โ€” a behavior known as "caudal luring" that takes advantage of the species' tendency to feed on lizards before transitioning to warm-blooded prey.

Common prey items

๐ŸฆŽ
Lizards
Skinks, geckos
The primary diet of juvenile GTPs โ€” caudal luring evolved specifically to attract these prey.
๐Ÿ€
Small Mammals
Native rodents
As GTPs mature, their diet shifts almost entirely toward small arboreal mammals.
๐Ÿฆ
Birds
Various species
Adult GTPs occasionally take small birds, particularly nestlings encountered during the hunt.
๐Ÿฆ‡
Bats
Various microbats
In the wild, GTPs have been observed taking small bats โ€” a unique example of arboreal predation.

Captive feeding

Feeding GTPs in captivity requires a more careful approach than carpet pythons. They are leaner, more compact snakes โ€” and they have a higher tolerance for fasting, but a lower tolerance for being overfed.

We exclusively feed frozen-thawed rodents, sized appropriately to the snake's body. For GTPs, "appropriate" tends to be smaller than what carpet keepers might be used to โ€” the prey item should leave only a slight bulge, never a dramatic distension.

A note on body condition
A healthy GTP is lean. The natural body shape is triangular in cross-section, with visible spinal ridges. New keepers often mistake this for "underweight" and overfeed accordingly โ€” a serious mistake.
