Peekaboo! This tiny frog was recently discovered by scientists in India. It’s one of seven new frog species they found. Four of the species are small enough to fit on a coin, making them some of the tiniest frogs ever known.
The newfound species belong to a group called night frogs. Scientists from the University of Delhi found them while exploring mountains called the Western Ghats. The frogs are nocturnal—active at night—and hide under leaves most of the time. These habits make them tricky to spot.
The mini frogs turned out to be plentiful in the region, says biologist Sonali Garg. “But they have probably been overlooked because of their extremely small size,” she says.
