Oligosoma alani

The robust skink, Oligosoma alani (formerly Cyclodina alani), is a large, rare species of lizard in the family Scincidae. The species is endemic to New Zealand.

Animal name origin

The specific epithet, alani, was given by the describer Joan Robb in honour of her nephew, Alan Robb.

Distribution

Geography

Countries
Biogeographical realms

O. alani was once widespread throughout the North Island but has been wiped out in most parts of its former range by predation from several species of introduced rats. It now occurs naturally only on six small islands off the north-eastern coast of the North Island.

Habits and Lifestyle

The robust skink is strongly nocturnal and lives under rocks, or in seabird burrows, tree stumps, and fallen logs. It prefers well vegetated areas with plenty of leaf litter and tolerates coastal areas as long as there is dense vegetation cover. Studies of the robust skink show that it is unusually vulnerable to losing water through its skin, which may explain its preference for damp environments such as crevices, bird burrows, rotting logs, and closely matted vegetation.

Lifestyle

Mating Habits

O. alani is viviparous.
