Scientists in Argentina have discovered the world’s first fluorescent frog, which emits a bright green glow when under UV light. Under normal light the frog is a dull yellow-brown colour with red dots. But when under UV light, experts found the fluorescent colour was so bright that even the frog’s organs could be seen.
According to scientists, the frog glows under UV light using both lymph and glandular secretions. The polka-dot frog is native to South America and was discovered near Santa Fe in Argentina.
Similar fluorescent qualities have been observed in other water-borne species but never in amphibians.
