See-through Glass Frog hides its blood
People can see the beating heart of the see-through Glass Frog. But, its blood is less visible. Scientists have recently discovered why. The Glass Frog hides its blood in its liver when it sleeps.
The Glass Frog (Hyalinobatrachium yaku) and the Fleischmann’s Glass Frog (Hyalinobatrachium fleischmanni) live in the tropical, dense Amazonian lowlands of Ecuador.
The size of a marshmallow, the amphibians are called Glass Frogs because their skin is translucent and transparent (see-through). Jesse Delia at the American Museum of Natural History in New York said to the New Scientist LIFE magazine in 2022, “If it wasn’t for that green skin on their back, you would probably be able to read a newspaper through them.”Continue reading “See-through Glass Frog hides its blood”
