Longer than 71% of all boas anyone has measured.
The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 109 to 6,700 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one
5 ft 2 in × 3 ft 5 in × 10 ft 4 in(158 × 105 × 315 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes snakes as a fraction of total length: 0.75 × 0.5 × 1.5.
Lives in vegetation, so height and climbing structure matter more than floor space.
Mindestanforderungen an die Haltung von Reptilien (Sachverständigengutachten), German Federal Ministry for Nutrition, Agriculture and Forestry, Animal Welfare Division, 10 January 1997. The standard states these floor areas are recommendations rather than binding limits.
From this animal’s own total length of 6 ft 11 in (2100 mm), at 0.75 × 0.5 × 1.5 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Garden Tree Boa. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
A prey item should be between the same width as the widest part of the snake's body and about 1.5 times that width.
Widely used across snake husbandry references. An alternative formulation gives prey at 10-15% of the snake's body mass. This is established practice, not a measurement.
307kJ per day
Worked out for an animal of 3,922 g, the heaviest recorded for Garden Tree Boa — so it is the top of the range, not a figure for a particular animal. Weigh yours and the number will be lower.
An upper estimate, not a feeding target, and not veterinary advice. The equation covers only what an animal burns staying alive, so a growing, gravid or recovering animal needs more — and it was measured on wild animals, which move far more than one in an enclosure. Body condition and a vet who knows the species are what a feeding decision should rest on. Where this comes from.
Morphs
0 with peer-reviewed genetics behind them, 2 resting on breeder consensus. Most references present both with the same confidence.
- Colour phasebreeder consensus
Where an animal sits in this species' enormous natural range of colour — grey and brown garden phase through to orange, red and yellow.
Worth knowing. A single clutch can contain garden-phase, orange, red and yellow animals from the same two parents. The colours are not single genes and no offspring percentage applies to them, so a breeder judges a pairing by what the parents look like and what their previous clutches produced.
- Patterningbreeder consensus
How strongly marked an animal is, from nearly patternless to boldly banded.
What nobody knows
These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
