World's first fluorescent frog discovered

Scientists have found that the South American polka-dot tree frog possesses a rather unique complexion.
The frog's unusual skin pigmentation was found entirely by accident by researchers who were studying the species at the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires.

Under normal light the amphibian's skin looks wholly unremarkable, but when it is exposed to an ultra-violet light it suddenly comes alive with a bright fluorescent green glow.


Fluorescence is actually quite rare in land animals and is mostly found in deep-sea creatures.

In this case the particular compound responsible for making the polka-dot tree frog's skin fluorescent had never even been seen before in any vertebrate species.

"This is very different from fluorophores found in other vertebrates, which are usually proteins or polyenic chains," said photochemist Maria Gabriella Lagoria.

The discovery suggests that other amphibians may also possess fluorescent skin as well.

I can see these being the next "In thing" at Raves and other parties with black lights.

Some bird feathers are florescent under black lights as well as the frogs too. I found that out in my teenage days of black lights and music with lights matching it. It was fun at sleepovers, so I can imagine pet frogs that glow would become a new in thing with black light parties.

Sheldon could have just had a few frogs in an aquarium instead of the glowing fish!
