This Is the Glass Frog, the Amphibian That Turns Transparent to Avoid Its Predators

While sleeping, the Fleischmann’s glass frog becomes between 34% and 61% more transparent to remain unnoticed by its attackers.

These nocturnal frogs forage for leaves during the day with which mixture Thanks to green pigment of his skin. However, this is not enough to avoid it, as when sunlight penetrates the leaves, it can reveal the silhouette of a frog. That’s why it’s exposed.

A team of scientists led by biologist Carlos Tabodafrom Duke University, noticed that these little amphibians have a really tempting trick go unnoticed to their attackers. When a Fleischmann’s glass frog sleeps, its transparency increases, to the point of being almost transparent.

“Glass frogs are known to have highly transparent muscles and abdominal skin, through which their bones and other organs are visible,” Taboda and colleagues write in their paper.

“We found that these fabrics transmit more than 90 to 95 percent of visible light while maintaining functionality. [como] activity [y] Vocalization. This transparency is adaptive because it camouflages the glass frogs from predators as they sleep on vegetation during the day.”

the study

Experts analyzed 11 Fleischmann’s glass frogs and used the technique of calibrated color photography To measure their transparency at different times: while sleeping, waking up, calling their mates, after exercising and under anesthesia.

The researchers found that the frogs maintained roughly the same level of transparency when awake, calling for mates, exercising, and under anesthesia. However, while sleeping they take turns between a 34% and 61% more transparent.

Optical spectroscopy confirmed that decreased red blood cells Circulating is the reason for the greater transparency of its lower parts. Experts Realize That Frogs Concentrate Most of Their Red Blood Cells liver at bedtime. When they wake up, red blood cells begin to circulate normally to continue their activity.

“The main result is that when glass frogs want to be transparent, which usually happens when they are at rest and vulnerable to prey, they filter out almost all the red blood cells from their blood and They hide in the mirror-coated liver, explains Sonke Johnson, professor of biology at Duke University, one of the researchers, “which somehow escapes, forming a larger blood clot in the process.”
