Naultinus tuberculatus

The West Coast green gecko (Naultinus tuberculatus ) is a species of the family Gekkonidae (gecko).

Appearance

This gecko has a "mossy" appearance due to the complex patterns of white and yellow shades on the background green coloration of the body. The eyes are quite small, and can be olive or brown. The mouth lining is a dark blue, and the tongue can either be black or dark blue. The toes, which the colour of range from being white to a yellow-green, are narrow and tapering. There is usually a small spot of light yellow at the corners of the mouth.

Length can reach 85 mm, snout to vent.

This gecko can be quite easily mistaken for the Nelson Green Gecko (N. stellatus), but can be distinguished by both the colour of the tongue and the shape of the snout. The tongue of a Nelson Green Gecko varies from being yellow to a warm orange; the snout is also longer and more shallow in comparison to the West Coast Green Gecko.

A $1 million project to replace Greymouth's ageing reservoir was halted in May 2021 because the site in Cobden needed to be searched for West Coast green geckos. The project manager stated (incorrectly), "No one has found one south of the Buller River yet, but DOC seems to think there are some here. These are the things that cause headaches."
