so they achieve camouflage by becoming super transparent. (Their livers, among other organs, are coated in highly reflective white crystals.) Since their red blood cells are transporting very ...

Glassfrogs make themselves transparent while they rest by taking red blood cells from circulation and concealing them in their livers. A multi-disciplinary team of biologists and biomedical ...

Red blood cells in the circulatory system make it difficult for most animals to become transparent. These cells are good at absorbing green light, which is the colour of light normally reflected ...

"If you really want to be transparent, you need to hide your red blood cells," study co-author Sönke Johnsen, a professor of biology at Duke University in North Carolina, told Live Science.

Those that are transparent include some fish, shrimp, jellyfish, worms and insects — none of which move large quantities of red blood through their bodies. The trick of hiding blood while ...

Taboada's team observed that red blood cells seemed to be disappearing from the circulating blood whenever the frogs became transparent. They conducted additional imaging tests on the animals ...

When tiny glass frogs turn in for the night, they're able to become transparent by hiding almost 90 percent of their red blood cells. The colorful areas are tucked away inside the frog's liver ...
