Cyclorana cultripes
Family: Hylidae
Common names: Grassland Collared Frog; Desert Collared Frog; Knife-footed Frog
Description: This frog is grey-brown, olive-brown or green on its back with darker patches. Most individuals have a pale stripe that runs down the spine. There is a dull stripe on the side of the head. A broad pale bar runs across the head, behind the eyes. The groin and the backs of the thighs are grey-brown mottled with white. The belly is coarsely granular and whitish. The skin on the back is smooth or warty. The toes are one third webbed.
Size: 50 mm
Habitat: This burrowing frog lives in grasslands and open woodlands. It usually only emerges after rain.
Call: A long harsh note. Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Takes place in January when the males gather in flooded grasslands and call from the edges of pools and creeks.
Similar species: This frog can be distinguished from Cyclorana cryptosis by its visible tympanum (tight membrane covering the entrance to the ear).
Conservation Information
Suspected threatening processes
- None stated
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: Trend unknown but population size suspected to be decreasing.
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 201-1000 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: 80,001-1,000,000 km² (up to 12% area of Australia or about the area of South Australia).
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.
