A tree-dwelling, day-active, meat-eating lizard from the Saharo-Sindian region, reaching 65 mm snout to vent.
Also called Derjugin's Lizard.
Once published as Lacerta derjugini — those names reach this page.

Longer than only 38% of all species in Lacertidae 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 35 to 444 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Anna Zimin: in observing tens of specimens they always climb vegetation or vertical walls in all their activity, sometimes I observed them entering and emerging from burrows in earthern walls - should be defined as arboreal(pers. comm. to SM, december 2023)

Keeping one
10 in × 6.5 in × 10 in(26 × 16 × 26 cm)
Minimum length × width × height, for one animal. Bigger is always better.
The standard sizes climbing species at 4 × 2.5 × 4 times snout-vent length.
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 snout-vent length of 2.5 in (65 mm), at 4 × 2.5 × 4 times it, following the German federal welfare standard — how this is worked out.
No preferred body temperature has been recorded for Artwin Lizard. Rather than repeat a number from a care sheet, this page leaves it out.
Feeding
A prey item should be no wider than the space between the animal's eyes.
Widely used across reptile husbandry references. The stated reason is that the gap approximates the width of the throat, so wider prey is associated with impaction. This is established practice, not a measurement.
1kJ per day
Worked out for an animal of 6 g, the heaviest recorded for Artwin Lizard — 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.
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.
