The Smooth-sided toad (''Bufo guttatus'', also known as ''Rhaebo guttatus'') is a species of toad in the Bufonidae family. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, rivers, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss. The smooth sided toad secretes a toxin from a gland behind their eyes known as a bufotoxin, it has been known to cause heart failure in humans if ingested. This toxin is the toads main line of defense against predators. ==References== * Azevedo-Ramos, C., La Marca, E., Hoogmoed, M. & Reichle, S. 2004. (Bufo guttatus ).
