The glowing frog is defined as one of the species of polka-dot tree frogs and lives in South America. According to Nature, a global leading weekly and international scientific journal, the frog displays a mixture of green, yellow and red under normal light, but gives off a blue and green glow under dim light. /VCG Photo

Researchers say that the frog uses fluorescent molecules to emit its glow, and it's the first case of natural fluorescence in amphibious tree frogs. /VCG Photo
