Longer than only 47% of all species in Diploglossidae 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 64 to 340 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

"Mollusca (land gastropod shells of at least two species included both crushed shells and an entire tiny shell), Myriapoda (Diplopoda: Spirobolida), Insecta (both larvae and adult Coleoptera, lepidopteran wing scales and larvae, legs of Orthoptera, and wings of cockroaches), and plant material (a piece of a small seedpod, tree bark, and small flowers). The female (MNHNSD 23.3949) regurgitated (during preservation) two caterpillars (lepidopteran larvae) and one winged termite (Blattodea: Isoptera)." Landestoy et al. 2022

Keeping one
17.5 in × 11 in × 17.5 in(44 × 28 × 44 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 4.25 in (110.1 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 Jaragua Forest 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.
3kJ per day
Worked out for an animal of 22 g, the heaviest recorded for Jaragua Forest 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.
