The species is native to the southern portions of the outlying New Caledonian island of Grande Terre.

[4] C. sarasinorum is currently being evaluated by CITES for protective status and is considered vulnerable to extinction in many herpetological circles.

[citation needed] Since there is a considerable variation in snout-to-vent length (SVL) of C. sarasinorum, which ranges from 3.5 to 5.5 inches (9 to 14 centimeters), it has been suggested that more than one subspecies exists; there is no universal consensus on this point.

[citation needed] The preferred natural habitats of C. sarasinorum are forest and shrubland, at altitudes of 20–600 m (66–1,969 ft).

[citation needed] The female C. sarasinorum lays two eggs which are buried in a soft, damp substrate.
