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 make up two separate species. Wikipedia →

Likely
About 50% of wildlife watchers report a Giant Marine Toad sighting in Cockscomb Basin Wildlife Sanctuary on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March, July and October
In those months about 60% of wildlife watchers report a Giant Marine Toad in Cockscomb Basin Wildlife Sanctuary on a given day, against under 5% in January, the lowest month. September has too few records to rate.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Giant Marine Toad sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
10th of 40
Of the 40 parks where we can rate Giant Marine Toad sightings, Cockscomb Basin Wildlife Sanctuary ranks 10th at about 50%. The best odds are in Piedras Blancas National Park (Costa Rica, about 60%), Tayrona National Natural Park (Colombia, about 60%) and Ostional Wildlife Refuge (Costa Rica, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Giant Marine Toad is recorded against all the amphibians logged in Cockscomb Basin Wildlife Sanctuary (18 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.
