The numbers

Thermal gradient

Day: a real gradient, 26–29°C warm against 20–24°C cool, so the animal chooses. Night: 10–18°C.

Why

Same scale on every sheet here, so two species compare by eye.

Day

Drag the sun. Jackson's chameleon is Diurnal, so what it is doing changes with the light. The sheet states a night temperature, and the rail follows it.

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 ».

Daily life

Behaviour and handling

HandlingMinimal: stresses easily
HousingSTRICTLY solitary; visual barriers
NoteColour = mood/health, not just camouflage

Health

When to see a vet

Cool highland chameleon: night temperature drop + dripper + T5 UVB, strictly solitary. Overheating is the top killer.

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.

Questions & sources

Common questions

Can it live in Bangkok?

It comes from cool mountain forest, so it needs a genuinely cool, airy room. Most Bangkok flats are too warm without air conditioning.

Can I hold it?

Better not. Handling stresses chameleons, so let it walk onto your hand only when you need to move it.

Are the horns dangerous?

No. Only the males have them and they are for pushing rival males, not for defending against people.

Does it need special equipment?

A tall mesh cage, live plants, a dripper or misting system for drinking, and UV lighting. It will not drink from a bowl.

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 420 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.
