The glass frog is a small arboreal amphibian that lives between Central and South America. It takes its name from the transparent nature of its body. During the day, to hide from predators, the frog empties its red blood cells and becomes transparent. The globules are stored in the liver for time of camouflage. This biological capacity arouses fascination among scientists. These movements of blood cells do not create blood clots, normally responsible for vascular problems like heart attacks. Scientists are wondering whether the glass frog wouldn't carry an antidote to heart attacks... a passionate story to follow! Photo credit: The Explorers
