Metacrinia nichollsi
Family: Myobatrachidae
Common name: Nicholl's Toadlet
Description: This frog is dark brown or black on its back, with dark markings and occasionally pink flecks. The belly is grey, blue or black with white spots or marbling. There is a bright yellow or orange spot at the base of each arm, in front of the thighs and at the base of the legs. The skin on the back is warty, while the belly is granular. The fingers and toes are not webbed.
Size: 25 mm
Habitat: This frog lives in karri and jarrah forests across the south coast of Western Australia and is often found under leaf litter and rotting logs.
Call: A short "ark" in spring and summer but most actively after rain or in mist in late summer.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © Dale Roberts.
Eggs: Are laid in damp leaf litter or beneath moist ground.
Similar species: This frog can be distinguished from Pseudophryne guentheri by its smaller size and the orange or yellow markings on its belly.
Conservation Information
Suspected threatening processes
- Inappropriate fire regimes
Population size: An estimate of the total number of adults present in the species entire range is >50000 individuals. Factors affecting population size and distribution are unknown or unsubstantiated.
Population trend in Australia over the past 50 years: Population size stable or suspected to be stable or increasing.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Not known to concentrate or exist in discrete locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: None directed primarily at the taxon.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 1-50 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is <2 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 1001-80000 km² (up to 1% area of Australia or about the area of Tasmania).
Distribution trend: Area occupied has declined by < 25%. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Broad range limits or habitat associations are known, but local occurrence cannot be predicted accurately.
