370:. They are found primarily along rainforest streams, near riffles, cascades, and waterfalls, as well as in wet sclerophyll forests. They have been observed perching on vegetation, rocks, logs, and roots along streams. During the day, they can also be found in piles of leaves beside flowing streams. They also have been found inhabiting similar streamside microhabitats outside of rainforests.

that there is simply less food available during drier seasons. Common mist frogs display sex-specific variations in foraging behaviour. This results in male and female common mist frogs having very different diets and eating patterns. Male mist frogs tend to have more restricted foraging activity than females and also display greater fidelity to a specific breeding site.
300:, meaning that one sex is larger in size than the other, in this case, the females are larger than males. Whereas males measure at around 31 mm in length, the female mist frog is on average 36 mm long. Similarly, the average adult male mist frog weighs an average of 2.0 grams while the adult female mist frog averages around 3.1 grams.

prey including insects and spiders. They are indiscriminate in their selection of prey, consuming what is most available in their habitats. Common mist frogs display a seasonal shift in prey selectivity, feeding even more indiscriminately during the dry season. This pattern is likely due to the fact
429:
Males have been observed foot-flagging, which is thought to be a way to communicate to other male frogs that they have encroached on the flagger's territory. Foot-flagging is when a male frog fully extends his back leg and foot into the air, then drags it back down against the ground. This behavior

The common mist frog formerly inhabited areas from sea level to mountainous areas reaching an elevation of 1200 meters. Since 1990 however, the mist frog can no longer be found above 600 meters and is rare in habitats above 400 meters elevation. The common mist frog's area of occupancy has now been

and in others their environment is largely protected from buildings and modern development. Additionally, a set of protocols designed to minimize the spread of diseases that threaten the common mist frog's survival has also been established. The movement of common mist frog tadpoles has also been

After mating, female common mist frogs deposit their eggs in gelatinous masses underneath rocks in fast-flowing water. About 46-63 eggs are laid beneath rocks, to prevent them from being washed away with the stream and are large and uncolored. The tadpoles are stream-dwellers, and have suctorial

To increase the probability of a successful mating, males display inter-male spacing. This is demonstrated by the males spreading out, with males rarely observed closer than one meter from another. The common mist frog's inter-male spacing is likely a territorial response to a low population of

Breeding occurs throughout the year, with peak calling occurring during the warmer season of the
Australian summer between November and March as the males are typically quieter in colder temperatures. Male common mist frogs have been observed to call from rocks and vegetation around streams and

during the colder months, especially in areas of higher elevation. By the mid-1990s, chytridiomycosis had eliminated the majority of common mist frogs at elevations greater than 400 meters above sea level. Habitat modification has also greatly impacted the species, with about 20% of tropical

The tadpoles have large mouthparts that they use to cling to nearby rocks. They also possess muscular tails that aid in swimming against a current. Common mist frog tadpoles have been described as torrent-dwelling, flat bodied, and with large suctorial mouthparts.
