Distribution and Habitat
Country distribution from AmphibiaWeb's database: New Zealand
Terrestrial; can be found in moist forests, grassy clearings, ridges, and sub-alpine scrub around 200-1000 m altitude. Nocturnal; likes to take shelter under stone and logs 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: Amplexus takes place in shallow depressions beneath logs, where it’s cool and moist. Egg clusters are later laid in strings. Diameters of egg capsules range from 8 to 11 mm. Eggs are yolky, unpigmented, and enclosed in clear capsules comprised of an outer, tougher, and initially somewhat adhesive coat, a middle gelatinous layer, and an inner vitelline membrane. 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).
