a field guide to the planet - by Damon Ramsey
The diverse amphibians of the tropical South and Central American rainforest...
Rhinella marina 'Giant Neotropical Toad', 'Marine Toad'. Large lumpy paratoid glands behind eyes. Has a gentle rolling call like a motorbike or generator in the distance. Usually found more on the edge of the forest. This is the infamous 'Cane Toad' that has been introduced in many tropical areas around the world and subsequently become a major pest, particularly in Australia.
