This Frog Has a Transparent Body and Hides Its Red Blood Cells While Sleeping #animal #shorts

Glass Frogs of Central and South America have transparent abdominal skin through which their beating heart, liver, and intestines are fully visible to the naked eye. A 2022 study in Science revealed that while sleeping, Glass Frogs actively pump up to 89 percent of their red blood cells into their liver, compressing them into a reflective cloak that makes the frog nearly transparent — dramatically improving camouflage against leaf backgrounds. When they wake, the cells re-enter circulation within minutes. A frog that achieves near-invisibility by temporarily storing most of its own blood.
