A day-active, meat-eating lizard from the Neotropic region, reaching 60 mm snout to vent.

Also called Orton's Anole.

Once published as Anolis bouvierii, Norops bouvierii, Norops ortonii — those names reach this page.

Body length across Anolidae

Longer than only 42% of all species in Anolidae anyone has measured.

33.5 mmthe whole family, smallest to largest191 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 33.5 to 191 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

9.5 in × 9.5 in × 9.5 in(24 × 24 × 24 cm)

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

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

Recorded both on the ground and climbing, so this is the larger of the two rules in every dimension.

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 2.25 in (60 mm), at 4 × 4 × 4 times it, following the German federal welfare standard — how this is worked out.

Active animals measured in the wild averaged 87 °F (30.8 °C).

Mean body temperature of active individuals measured in nature. A measurement of the animal, not a setting for a thermostat.

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 5 g, the heaviest recorded for Bark Anole — 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.
