MacDougall's Tropical Night Lizard

No photograph of this species exists under a license anyone may reuse. It gets the same page regardless.

A rock-dwelling lizard from the Neotropic region, reaching 56 mm snout to vent.

Once published as Gaigeia dontomasi — those names reach this page.

Body length across Xantusiidae

Longer than only 33% of all species in Xantusiidae 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 36 to 153 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

8.75 in × 8.75 in × 5.5 in(22 × 22 × 14 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.

Lives on rock, so stable hard surfaces and basking ledges suit it.

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 (56 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 MacDougall's Tropical Night Lizard. Rather than repeat a number from a care sheet, this page leaves it out.

Feeding

1kJ per day

Worked out for an animal of 3 g, the heaviest recorded for MacDougall's Tropical Night 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.
