Bilbo's rain frog (Breviceps bagginsi) is an amphibian species in the family Brevicipitidae, endemic to South Africa.

The ventrum (underside) is white with subtle flecks, transitioning to more prominent darker mottling in the throat region.

They live on edges of wood plantations in Kwazulu-Natal midlands of southeastern South Africa along the mist belt from Boston in the west to Melmoth in the north-east and down to the coast at Mkambati.

This discovery leads to the possibility that the species' distribution is expanding southward, potentially reaching the Port St Johns area.

Their populations are heavily fragmented, and their habitat quality is declining due to forestry operations and road construction and maintenance.

Due to the frog's sensitivity to dry heat, mating calls last longer during cooler wetter weather.

[8] Offspring also develop further in the burrows, as rain frogs do not have a free-swimming tadpole stage, and emerge from them once fully mature.

[18][20][8] Breviceps also secrete a sticky white substance from their skin, and sometimes emit a harsh shriek as a defense mechanism.

[18] Breviceps bagginsi is both a terrestrial and fossorial amphibian, and therefore it spends a great deal of time in its burrow, but once termites emerge they leave their nests to feed.

[9] Breviceps bagginsi is an insectivore, and they also feed upon ants, beetles, moths, woodlice, amphipods, juvenile millipedes, caterpillars, and other small arthropods.

Furthermore, Breviceps bagginsi live in extremely fragmented subpopulations and the quality of their habitat is decreasing due to sylviculture and construction and maintenance of roads.
