Body length across Cordylidae

Longer than 96% of all species in Cordylidae anyone has measured.

96% of 67 species are smaller4% larger
68 mmthe whole family, smallest to largest220 mm

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 68 to 220 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

What is known

33 sourced facts, each taken from a named scientific dataset. How to read these.

Cited from a dataset unless a row is marked otherwise.

Two of these figures disagree

Body mass (adult female, mean) is given as 59.6, and Body mass (greatest) as 19 — but an average female cannot outweigh the heaviest animal recorded. They come from different sources and both are shown exactly as those sources give them.

Keeping one

2 ft 2 in × 2 ft 2 in × 16.5 in(66 × 66 × 42 cm)

Minimum length × width × height, for one animal. Bigger is always better.

The standard sizes ground-dwelling species at 4 × 4 × 2.5 times snout-vent length.

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 6.5 in (166 mm), at 4 × 4 × 2.5 times it, following the German federal welfare standard — how this is worked out.

No preferred body temperature has been recorded for Large-scale Grass 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 19 g, the heaviest recorded for Large-scale Grass 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.
