A ground-dwelling, day-active, meat-eating skink from the Oriental region, reaching 78 mm snout to vent.
Also called Christmas Island Whiptail-skink.

Longer than 57% of all skinks 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 24 to 500 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one
Forest skink is assessed as Extinct on the IUCN Red List. No living animal is known. Anything below describes what was recorded of the species while it existed, and it is here because a reference that quietly drops a species it has lost is a worse record than one that keeps it.
No enclosure size, temperature or feeding figure is given for this species. What is recorded about the animal stays on this page above; advice on keeping one does not, because there is none to keep.
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 10 g, the heaviest recorded for Forest skink — 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.
