Natural History:
The Sharp-Nosed Toad is one of the few species to have become separated from the Crested Forest Toad complex (Rhinella margaritifer complex). This complex is believed to be made up of several unsubscribed species lumped together as one. The Sharp-Nosed Toad can be differentiated from the Crested Forest Toad complex by its pointed fleshy snout along with relatively smooth skin, the Sharp-Nosed Toad also lacks the spines present on the Crested Forest Toad's sides. This species was differentiated from the complex due to their difference in genetics and lack of inbreeding with other toads in the complex.
Like the Crested Forest Toad, the Sharp-Nosed Toad is diverse in its colouraiton and patterns with some individuals being grey while others may be brown to orange-ish in colour. Their pattern also changes from one individual to the next with many having blotches or a stripe running down their back to mimic the vein of a fallen leaf.
Sharp-Nosed toads are primarily found during the day (although ones found at night are not unheard of) where they inhabit the forest floor of primary and secondary forests as they feed on a wide variety of invertebrates and tend to be found in areas with high biodiversity. Come the breeding season, many Sharp-Nosed Toads leave the forest and congregate along streams where they breed en masse. Breeding takes place in small pools of water close to streams and rivers. This way, when the water levels rise during the wet season the tadpoles, once old enough, are able to move into open water where they have to fend for themselves. Because there is a high number of predators, toads will deposit several hundred eggs to increase the chances of some surviving to adulthood.
While the Crested Forest Toad is found throughout much of the Amazon basin, the Sharp-Nosed Toad is only found in the western portion of the Amazon rain forest. Their range extends from central Loreto in Peru to central Ucayali, also in Peru. They also have two populations in south eastern Colombia, another one in north eastern Ecuador and one where Peru boarders with both Brazil and Colombia.
