Common mist frog

[1] The common mist frog is found in remote, mountainous areas, and near rocky, fast-flowing rainforest streams such as those in north-eastern Queensland, Australia.

[1] The common mist frog is a dull grey or brown color in appearance, with tubercles (small rounded protrusions) and dark, irregular markings on its dorsal surface.

[3] The common mist frog has obscure dark bands that run along the side of its snout from the eye and ear to the shoulder.

[6] The common mist frog inhabits the riparian zone of fast-flowing streams in rainforests and wet sclerophyll forests of eastern tropical North Queensland.

[8] After mating, female common mist frogs deposit their eggs in gelatinous masses underneath rocks in fast-flowing water.

The diet of common mist frogs consists of a range of terrestrial and aquatic prey including insects and spiders.

Male mist frogs tend to have more restricted foraging activity than females and also display greater fidelity to a specific breeding site.

[8] A key factor that is largely responsible for the common mist frog's endangered status is chytridiomycosis, a disease that is caused by the chytrid fungus Batrachochytrium dendrobatidis.

This parasitic fungus attacks the skin cells of amphibians and disrupts their osmoregulatory and transport functions, altering electrolyte concentrations in the blood.

The disease can ultimately cause cardiac arrest once the fungal population on the host organism reaches a high enough density.

Common mist frogs are more vulnerable to infection by B. dendrobatidis 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.

[5] Populations of the common mist frog have declined since 1990 and it is classified as an endangered species by the International Union for Conservation of Nature (IUCN) since in 2001.

Additionally, a set of protocols designed to minimize the spread of diseases that threaten the common mist frog's survival has also been established.
