Part of this is not on the page we cite. We opened it on 10 Aug 2026 and some of the degrees above are not stated there. The values above may still be right, but we cannot show you where they came from, and nobody here has checked them against a second source. Anything about a sick animal goes to a qualified exotic vet, not to a page. reptifiles.com

Day

Drag the sun. Brazilian Rainbow Boa is nocturnal, so what it is doing changes with the light. The sheet states a night temperature, and the rail follows it.

Semi-terrestrial · temperate · humidFrom the sheet: 27–29°C, humidity 70–80%

The way of life is written in this sheet, word for word. The climate words summarise the two figures above them, they do not add to them.

CITES II is a global listing and holds in every country. National law is not global, and we hold no national wildlife law for any country, Thailand included. Check your own authority before buying or selling.

The warm side, 27–29°C, dropping to 24–26°C at night. This sheet states the warm side only. It gives no cool side, so the other end of the gradient is not in our data. Same scale on every sheet here, so two species compare by eye.

The size the sheet states for a grown animal.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

How common this animal is

6,230Live individuals in declared US trade filings

NOT a measure of how many are kept. These filings count animals shipped for any purpose, including the food trade and laboratory supply, and they are United States records only. The three largest volumes in the source belong to a food frog, a bait species and the standard laboratory amphibian.

Drawn from the stated numbers. Only what the sheet states is drawn inside.

Why

The rectangle carries the exact width-to-height ratio of the figures above it, and the ruler under it places that width on the 0–250 cm scale every sheet here shares, so two species still compare at a glance. Nothing is added that the sheet does not name: a lamp drawn on a sheet that never mentions one would be invented equipment. What the sheet leaves out is listed rather than left blank, because an empty tank reads as « none needed ».

Diet

Feeding rhythm

Juvenile
every 7 d
Adult
every 10–14 d
2Meals in 28 days · adult

Twenty-eight days, one row. Each band is a meal window. This sheet states a figure for each age, so each age has its row.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56. A young animal's row is drawn only where the sheet gives one: working it out by dividing the adult interval would be inventing a ration.

Read from the lifespan and maturity the sheet states, for animals in care and not in the wild.

Why

The minimum commitment is the low end of that lifespan, and the reproductive window is what is left after maturity: both are subtractions on stated figures, not figures of their own.

When to see a vet

This is not veterinary advice. If red flags appear (open-mouth breathing, months of weight loss, 'stargazing', persistent regurgitation) consult a qualified exotic (herp) veterinarian. Quarantine new arrivals 30–90 days.

Good to know

  • Iridescent scales split sunlight into a rainbow sheen.
  • Live-bearing and among the most beautiful boas kept.
  • A true rainforest species: high humidity is essential.

Common questions

Why is humidity so important?

Too dry causes shed problems and respiratory infection.

Does it stay small?

Mid-sized (1.5–2 m): manageable.

Beginner snake?

Better as a second snake: humidity is exacting.

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

Every field this product runs on is stated here. That is not a claim that the values are right: it says what the sheet states, not whether it is true. Whether a human has read it is the badge at the top of this page.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
