Abstract

The article focuses on the diverse structures of vocal sacs in frogs and toads, highlighting research conducted by herpetologists Agustín Elías-Costa and Julián Faivovich. They discovered that there are 20 basic forms of vocal sacs among the 4,358 species studied, with about 18 percent lacking vocal sacs entirely. The researchers examined 777 specimens over a decade, revealing that vocal sacs have evolved and disappeared numerous times within the frog and toad family tree. The study emphasizes the ecological implications of these variations, as different environments influence the types of vocal sacs that are advantageous for mating calls. [Extracted from the article]
