The majority of the world's 5,000+ frog species are found in tropical forests.
Frogs — toads are a subset of frogs — are amphibians.
Like other amphibians, frogs are declining worldwide due to pollution, habitat loss, climate change, introduction of alien species, and the outbreak of a devastating fungal disease known as chytridiomycosis. More than 100 species are known to have gone extinct since the 1980s and more than one third of the world's remaining species are considered endangered according to the IUCN Red List compiled by scientists.
The giant monkey frog of Peru is known for its mind-altering skin secretions. Shamans in the Amazon rain forest have used this species in hunting rituals.
