Juan Manuel Guayasamin (born 1974) is an Ecuadorian herpetologist. He earned his Ph.D. in 2007 from University of Kansas, Department of Ecology and Evolutionary Biology and as of 2017 he is working as professor at Universidad San Francisco de Quito in Ecuador. His research interests include the evolution of glass frogs (Centrolenidae) and direct-developing anurans. His main contributions have been: phylogenetic taxonomy of glassfrogs, description of the variation of skin texture in frogs, description of numerous species of amphibians and reptiles, and a monographic review of all Ecuadorian glassfrogs (60 species). A team led by Juan M. Guayasamin discovered Hyalinobatrachium yaku in May 2017, a glassfrog with transparent venter. [1] To date (2020), he has described a total of 6 amphibian genera, 55 species of amphibians, and 11 reptiles, including two geckos from the Galápagos Islands.

Glass frog family of amphibians

The glass frogs are frogs of the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin, hence the common name is given as glass frog. Glass frogs are arboreal, meaning they mainly live in trees, and only come out for mating season.
