Rhinella horribilis
Rhinella horribilis is the scientific name used for populations of the cane toad or giant toad located in Mesoamerica and north-western South America when they are considered to be a separate species from "Rhinella marina", a name which is then mostly restricted to Amazon basin populations. "R. horribilis" was originally described from Mexico as "Bufo horribilis" before later being considered a synonym of "Bufo marina" and later "Rhinella marina". The specific epithet "horribilis" has now been revived after a 2016 study argued that these populations in fact make up two separate species.
