Physical description

The Common Eastern Froglet is a small frog (3 centimetres), of brown or grey colour of various shades. The frog is of extremely variable markings, with great variety usually found within confined populations. A dark, triangular mark is found on the upper lip, with darker bands on the legs. A small white spot is on the base of each arm. The dorsal and ventral surfaces are very variable. The dorsal surface may be smooth, warty or have longitudinal skin folds. The colour varies from dark brown, fawn, light and dark grey. The colour of the ventral surface is similar to the dorsal surface, but mottled with white spots. In anatomy, the dorsum is the upper or back side of an animal, as opposed to the ventrum. ... In zootomy, several terms are used to describe the location of organs and other structures in the body of bilateral animals. ... A close-up of human skin. ...

Ecology and behaviour

The Common Eastern Froglet will call within a large chorus of males close to a still water source, or slow flowing creek. The call of the male is a crik-crik-crik, this is heard all year round, during wet and dry conditions. An average of about 200 eggs are laid in small clusters attached to submerged vegetation, the tadpoles and eggs survive in 14–15 °C water. Tadpoles are normally brown and reach about 36mm in length, development is relatively short, however it is dependent on environmental conditions. At a temperature of 15°C development can range from 6 weeks to more than 3 months. Metamoprh frogs are very small, about 8 mm.

The diet of the species consists of small insects, much smaller in comparison to their size to most frogs.
