Brachycephalus brunneus is one of the smallest frog species in the world. It lives in the mountain forests of Brazil, has a bright body coloration about one centimeter long and breathes mainly through the skin.
Brachycephalus brunneus differs from related species by its very small body size and absence of lungs. The species is important for nature as part of the biodiversity of the Atlantic Forest and a participant in the food chain of small invertebrates.
