The name says it all: glass frogs are transparent. Through the skin on the stomach you can see their organs. Now, researchers from the Universidad San Francisco de Quito in Ecuador have discovered a hitherto unknown specimen of glass frogs. The scientists have christened the two-centimeter frog Hyalinobatrachium yaku . It is one of the few representatives of his family whose heart does not know, but red through the skin - and which can be observed when hitting. Even small veins can be seen.
The recently discovered frog is not only exceptionally transparent, it also stands out for its special reproduction behavior. "The males take care of the eggs that are placed under tree leaves - until they break loose and fall into the water underneath, " explains biologist Juan Guayasamin of the Universidad San Francisco de Quito. "I work with frogs every day and this is one of the most beautiful specimens I've ever seen." Guayasamin and his colleagues suspect that Hyalinobatrachium yaku from Ecuador is already threatened with extinction as humans invade their habitat.
