Taudactylus eungellensis
Family: Myobatrachidae
Common names: Eungella Day Frog; Eungella Torrent Frog
Description: This frog is yellowish-tan to dark brown on its back with darker mottling. There is a pale bar between the eyes with a dark brown bar behind it. A pale stripe runs from the eye to the arm and there is a dark X-shaped mark on the back between the shoulders. The arms and legs have dark banding. The belly is smooth and yellow. The skin on the back is smooth, granular or with a few low warts. The toes have wedge-shaped pads and no webbing.
Size: 35 mm
Habitat: This frog lives in montane rainforests and tall open forests. It is found in and around flowing streams, which it readily dives into when alarmed. This frog is able to cling beneath rocks in swift torrents until danger has passed.
Call: A soft "cluck-cluck-cluck-cluck" repeated in short bursts.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Males call with greatest intensity during spring and summer. The eggs are laid in jelly-like clumps under rocks in the water.
Eggs: Are large and laid in masses of 30-50 under rocks in streams.
Tadpoles: Are orange brown, with a distinctive V-shaped marking behind the eyes.
Similar species: This frog is most similar to Taudactylus diurnus but they can easily be separated on distribution.
Other characteristics: Males of this species have been observed communicating by visual cues, such as flicking and waving of legs, head bobbing, and distinctive hops.
Conservation Information
Suspected threatening processes
- Disease/pathogens (e.g. chytrid fungus, viruses)
Population size: An estimate of the total number of adults present in the species entire range is 0-1000 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 known to be decreasing.
Knowledge of population trend in Australia: Nation-wide monitoring, but not with statistical sensitivity.
Population concentration: Majority concentrates at more than 25 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: Management mostly related to enforcement of conservation laws.
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: 101-1000 km².
Distribution trend: Area occupied has declined by 75-100%. (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.
