No country has more amphibians than Brazil – at least 800 species of frogs and toads were described in the country. You will find an updated list of Brazilian amphibians plus lots of great pictures at Anfíbios e Répteis do Brasil website.
The group is under menace – amphibians are among the fastest disappearing animals, both nationally and internationally -, mainly because of the destruction of their habitats by construction or agriculture, but also because of pesticide contamination and climate change. In recent years, an unexpected series of frosts extinguished at least five frog species in the Southeast region of Brazil.
