AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. [1] It added its 7000th animal in 2012, a glass frog from Peru. [2] [3] As of 2022, it hosted more than 8,400 species located worldwide. [4] [5]
