Glass frogs do not live a life of modesty. With their semitransparent skin—green on the back, clear on the belly—the tree-dwelling, gummy-bear-size amphibians, which are native to the tropics ...

Glass frogs are one of just a few land-based vertebrates that can become transparent, which has made researchers particularly interested in them, but few have understood the process until now.

Glass frogs, the new research suggests, can control when their blood clots. If they are wounded, they will form a scab in the usual way. But when they are asleep, with red blood cells packed like ...

When tiny glass frogs fall asleep, they store almost 90 percent of their red blood cells in their liver, increasing the animals’ transparency (seen in the first clip), which may help hide them ...

Of course, researchers are still puzzled over how the glass frog survives such a state for up to 12 hours each day. Though plasma, the colorless part of blood, still circulates during this time, red ...

10. They Are Mainly Threatened by Deforestation . Glass frogs have plenty of predators, from giant wasps to snakes, but the most significant risk to their existence is the loss of habitat from ...

The northern glass frog, which ranges from southern Mexico to Ecuador, even conceals its blood to render its body more ...

The glass frog, found throughout southern Mexico, Central America and South America, is distinguished by the translucency of its underbelly, through which it is possible to see the frog’s internal ...

Glass frogs can turn on their transparent appearance by hiding 90% of their red blood cells in their liver during sleep, a new study in Science reported Thursday.

Dec. 23 (UPI) --Researchers say they have solved the mystery of how glass frogs become mostly transparent while they sleep. The discovery may lead to innovations in how to understand blood clotting.

A frog that turns to a mostly translucent state when sleeping could hold the key to understanding human blood coagulation. Although the glass frog has long been recognised by science, its method ...
