The smooth-sided toad (Rhaebo guttatus), also known commonly as the spotted toad, is a species of amphibian in the family Bufonidae. It is native to the Amazon basin of South America. The first description of the species was published in 1799 by Johann Gottlob Schneider, who placed it in the genus Bufo. Edward Drinker Cope moved the species to the genus Rhaebo in 1865.
The species taxonomic status is unclear, as it is likely that Rhaebo guttatus as currently defined actually encompasses several distinct species of toad. Rhaebo glaberrimus was for a time considered a subspecies of Rhaebo guttatus. Some specimens from southern Peru, Bolivia, and Brazil that were considered to belong to the species may actually represent Rhaebo ecuadorensis, the first description of which was published in 2012.
Males growth to about 15 cm (5.9 in) snout–vent length. Females are larger, at up to 17.4 cm (6.9 in), possibly even 25 cm (10 in), in snout–vent length. The dorsal color is cream colored or very light brown to reddish brown. The belly is a darker shade. The species has a characteristically prominent preocular ridge that is present even in juveniles.

Very likely
About 70% of wildlife watchers report a Smooth-sided Toad sighting in Brownsberg Nature Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 18 amphibians we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
April and November
In those months about 80% of wildlife watchers report a Smooth-sided Toad in Brownsberg Nature Park on a given day, against about 20% in October, the lowest month. June and August–September have too few records to rate.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Smooth-sided Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 4 parks where we can rate Smooth-sided Toad sightings, Brownsberg Nature Park has the highest daily chance: about 70%. Next come Yasuní National Park (Ecuador, about 40%) and Manu National Park (Peru, about 20%).
Same family: Bufonidae
The closest relatives of the Smooth-sided Toad that you can see in Brownsberg Nature Park (family Bufonidae, True Toads) are Eastern Cane Toad (about 70%), Hoogmoed's Harlequin Frog (about 40%) and Crapaud De Merian (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Smooth-sided Toad is recorded against all the amphibians logged in Brownsberg Nature Park (26 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
