Mixophyes fasciolatus
Family: Myobatrachidae
Common name: Great Barred Frog
Description: This frog is dark grey or brown on its back with darker blotches. There is an irregular dark brown band (often broken into blotches) starting between the eyes and running down the back. A dark stripe on the head starts in front of the nostril and continues through the eye to the tympanum (tight membrane covering the entrance to the ear). The arms and legs have dark bars which widen under the legs to form a triangular pattern. The sides of the body have dark spots and blotches, and the skin on the back is finely granular. The iris is dark brown. The belly is smooth and white. The toes are three-quarters webbed.
Size: 80 mm
Habitat: This frog lives in forests such as Antarctic Beech, wet sclerophyll and rainforests. It often hides in leaf litter near permanent fast-flowing streams.
Call: A deep harsh "wark".Call available in

Breeding: Males call in spring and summer from the banks of streams, amongst the leaf litter. Once the eggs are fertilized, the female tosses them out of the water and onto the bank. The eggs have a sticky coating and stick easily to leaves, rocks and grasses. Once the tadpoles hatch they drop into the water or get washed in when it rains.
Eggs: Are large and attach to leaves, rocks and grasses above the surface of the water.
Tadpoles: Are large and dark golden-brown to grey-brown in colour. In flowing water these tadpoles can attach to rocks and other surfaces using their mouths.
Similar species: This frog can be distinguished from others species of Mixophyes by the spots on its sides, its dark brown iris, and the triangular pattern on the backs of its thighs.
Conservation Information
Suspected threatening processes
- Habitat modification (e.g. vegetation clearing, invasive weeds)
Population size: An estimate of the total number of adults present in the species entire range is >50000 individuals. Some factors affecting population size and distribution are known, but 1 or more major factors are unknown.
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: Monitored locally.
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 2-3 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: Distribution is well known and occurrence can be accurately predicted throughout the range.
