McCanns skink

Status: Not threatened

Description

McCann’s skink (Oligosoma maccanni) mokomoko (Māori) is a small to medium endemic skink that grows up to 73mm. Its dorsal (back) is grey or light brown, either uniform, patterned or striped. If patterned, the pattern may be herringbone or chequered; if striped, the stripes may be smooth or notched. Mid-dorsal stripe, if present, may become broken, notched or wavy on the tail. Lateral surfaces with a broad dark brown stripe, upper, bordered by either smooth or notched thin white stripes; below this, grey or grey-brown. Ventral (belly) surfaces whitish-grey or yellow, usually uniform but may be finely speckled with black. Throat whitish-grey, usually finely speckled with black.

Being cold-blooded, it needs warmth to digest food and is commonly seen basking in the sun on warm rocks. 

Ventral (belly) surface is usually speckled or uniform. The eyes are light olive-grey or brown, and those in Hawea/Wanaka have pale blue or green edge. The mouth is pink, and the tongue is pink with a grey tip.

Conservation efforts

Note: trapping that removes larger predators such as weasels, ferrets, stoats, and cats has the potential to increase the population of mice, which can have a devastating effect on reptiles and invertebrates.
