Distribution and Habitat
Country distribution from AmphibiaWeb's database: New Zealand
Terrestrial; can be found in coastal forest and deep boulder banks. Nocturnal; likes to take shelter in damp crevices by day (Gill and Whitaker 1996).
Life History, Abundance, Activity, and Special Behaviors
Defense: Can remain motionless for long periods of time. Assumes stiff-legged stance, rearing up and extending the legs (Green 1988).
Reproduction: Sometimes frogs, particularly males, occupy the oviposition sites for weeks or longer prior to the laying of eggs. Takes froglets at least 3 to 4 years to reach maturity. In their development, they have narrow tail fins, and only the base of the forelimbs is covered by the gular fold (Bell 1978).
