The species

Identity

Adult size

True scale, against a 1.75 m person

Logarithmic, the same axis on every sheet

6–8 cmNose to tail, adult

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.

What this sheet states

46%
TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 4 of 7 of the fields this product runs on. What is missing turns something off: thermal rail and temperature audit, humidity instrument and audit, enclosure size audit. We show the gap rather than fill it with a plausible number.

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.
