This tiny species of critically endangered frog inhabits the rainforests of Tanzania, and more specifically, they can only be found in the Nguru South Forest Reserve up in the Nguru Mountains. These frogs belong to the family Brevicipitidae, which are commonly known as rain frogs. Frogs in this family spend most of their time buried underground or under the leaf litter, so not a whole lot is known about them or their behavior in the wild. Though this species, as well as some other members of Breviciptidae, are surprisingly good climbers compared to other frogs in their family. The fact that this species has such a small range, which is only becoming smaller and smaller due to habitat loss, makes it even harder for scientists to observe them in the wild.

Like many other frogs, the females are much larger than the males. This is because males will ride on the backs of the females during the breeding season and glue themselves together using a special secretion that males produce from a gland on their vents and females from a gland on their backs. This helps prevent the pair from being separated by a rival male before they are able to mate. Interestingly, some species of rain frogs, such as those in the Breviceps and Probreviceps genera, don't go through a tadpole stage and instead emerge as tiny froglets right out of the egg. While it's currently unknown if the Nguru warty frog also skips this stage, many herpetologists suspect that it does, along with many other species of breviciptine frogs.
