Glassfrog has nothing to hide
A newly discovered species of Amazonian frog has skin so transparent you can see its heart beating.
From above, this tiny green-spotted frog appears quite ordinary. Turn it over to reveal its transparent ventral skin and exposed beating heart, and it emerges as anything but.
While there is an entire group of glassfrogs from the Neotropics – the tropical regions of the Americas – who sport impressive transparent skin and exposed bellies, this new species, Hyalinobatrachium yaku, stands out for the extent of its translucent exterior, stretching right across the abdomen to lay bare the body’s inner workings.
