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 ...

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.

Glass frogs can boost their transparency by up to 61 per cent by storing most of their blood in their liver while they sleep. Researchers hope that understanding how the frogs manage to pool their ...

Amphibians like glass frogs become see-through whilst sleeping - and now scientists have discovered how. The creatures hide 90 per cent of their red blood cells in their liver, which is mirror ...

About 89 percent of the frogs’ red blood cells had packed themselves into that organ. That made sense: The liver, which filters blood, is a logical destination for red blood cells, he said.

The researchers found that, when asleep, the frogs remove nearly 90 percent of their blood cells from circulation and store them in their liver, which contains reflective guanine crystals ...

Using calibrated color photography and photoacoustic imaging, researchers on a new paper were able to establish that glass frogs become 34 to 61 percent more transparent by removing roughly 89 ...

How the frogs’ tissues endure their bizarrely bloodless state for hours at a time is still a mystery. “If I took 89 percent of your blood and put it in your liver at night, you’d probably be ...

But for glass frogs and other invertebrates, the greatest challenge to translucency is their red blood cells, which naturally absorb light. Until recently, in fact, precisely how glass frogs wove ...
