Brazilian Spinythumb Frog

Fascinating facts about the Brazilian Spinythumb Frog

• A French botanist’s surname lives on a Brazilian frog: the species name gaudichaudii honors Charles Gaudichaud-Beaupré, linking plant science to amphibian discovery. It shows how taxonomic tributes can bridge very different fields of nature.
• You can find this frog from the shoreline up to 1,800 m (5,900 ft) in the mountains, thriving in both lowland rainforests and mist-shrouded montane forests of Rio de Janeiro and São Paulo. Its altitude range reveals a surprising flexibility for a creature often thought to stay in one niche.
• Rivers are part of its habitat, and habitat loss puts the species at risk.
