Heloderma suspectum

Traceable. The figures above appear in the page we cite, which we opened on 10 Aug 2026. That means you can check them, not that we have confirmed they are right. kingsnake.com

Drag the sun. The sheet states a night temperature, so the rail follows it.

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.

Day: a real gradient, 29–32°C warm against 24–27°C cool, so the animal chooses. Night: 21–24°C.

Why

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

Not stated: The size of the enclosurethis sheet states no size

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.

What this sheet states

62%
TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 4 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit, day/night engine and awake count on the globe, the diet section. We show the gap rather than fill it with a plausible number.

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.
