World’s first fluorescent frog that glows bright green is found in Argentina
Under normal light the polka-dot tree frog is a dull green/brown colour.
But scientists stumbled upon the species’ rare ability under their UV torches.
It is rare for land animals to have fluorescent skin pigments.
The pigments absorb light and re-emit it at longer wavelengths.
