00:04This is what is known as a glass frog, a breed of amphibian, indigenous to Mexico and areas of South
00:10America and the Caribbean.
00:12They're called glass frogs because they can do this, literally become transparent when they sleep, to give themselves some camouflage
00:18while they rest.
00:18And for the first time, scientists not only believe they've figured out how it works, but it could have far
00:23-reaching medical implications for humans.
00:25The researchers found that glass frogs are able to separate 90% of their red blood cells and force it
00:30all into their livers, which just so happens to be mirror-coated.
00:33Red blood cells are almost impossible to hide because they're extremely good at reflecting green light.
00:38With the researchers writing, quote,
00:39Whenever the frog needs to become active again, they bring the cells back into the bloodstream, which gives them the
00:44metabolic capacity to move around.
00:46And they say that figuring out just how these creatures' extreme physiology works might also help to solve some medical
00:51issues in humans.
00:52Blood clotting of red blood cells is an issue that can lead to heart attacks and strokes,
00:57meaning discovering the triggers that glass frogs employ to sort their blood could help doctors prevent blood clots in humans
01:03in the future.
