Rhinella proboscidea is a species of small South American toad in the family Bufonidae, common in the Amazon rainforest.

Taxonomy
The specific name derives from the Latin proboscis (elephant trunk), in recognition of the toad's prominent beak. It is a member of the R. margaritifera species complex.
The species was first described under the name Bufo proboscideus by Johann Baptist von Spix in 1824. Spix collected the holotype specimen near the Solimões River during his journey to Brazil. It is now held by the Zoologische Staatssammlung München.
In 2006, members of the Bufo margaritifera complex were recognized as the new genus Rhinella, leading to the current name. The merge of another genus into Rhinella left a different species sharing this name (homonymy), which was resolved by renaming the other species Rhinella boulengeri (now Dendrophryniscus proboscideus).
Distribution
This toad is found in Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests and intermittent freshwater marshes. It is threatened by habitat loss. It is common in parts of the Amazon rainforest.
Characteristics
Males are 46–54 mm with smooth skin, while females are 46–55 mm with granular skin. The dorsal surface is reddish or dark brown, and typically spattered with black and brown patches. It has a triangular head with a pointed snout, and a brown to gray belly.
This toad is mostly active during the day, sleeping on small seedlings and shrubs at night, but shows nocturnal activity during the breeding period. Its tadpoles are light brown and similar to other R. margaritifera tadpoles. The skin is highly toxic, but predation by a snake (Xenoxybelis argenteus) has nonetheless been observed.
This species is an explosive breeder that reproduces in shallow pools off the edge of streams. The toads gather in these locations for two or three days, where they collectively fertilize thousands of eggs. A typical reproductive period is from March to May, but it could vary depending on rainfall. After heavy rain, choruses of as many as 100 male R. proboscidea calling for a mate have been heard.
