VOICED : El sapo ecuatoriano que rompió el silencio con canto después de un siglo

For decades, scientists believed a small frog species was mute until a biologist heard its unique bird-like song in 2016. This discovery, published in Neotropical Biodiversity, challenged the notion that the species couldn't sing due to its vocal anatomy. The frog, known as the Valle de Santiago toad, lacks vocal slits and sacs, making its singing ability unique. Found in the Amazonian ranges of Cutucú and Cóndor, it measures 45-68 mm and has a distinctive nasal prominence. The discovery suggests all toad species might sing, challenging previous assumptions about silent groups. In other species, croaking is linked to courtship and territory defense, but for these toads, it's an announcement, akin to a calling card.
