Which of the following characterises the polka-dot tree frog that lives in the Amazon river basin?

I wish they had included a photo of the frog under UV light.

Black light or UV light?!

yeah RusPus even my dog knew this nature question and black light shines blue making the animal glow in the dark. you big cat,King of the African Plain.

Smeeg, Those of us from the late 60’s know, where walls everywhere were plastered with “black light posters” for art….? 🤣

This is why I'm not a scientist. It would never occur to me to put a black light on a frog.

RusPus, it's the same thing. Americans tend to call it black light, British and Europeans tend to call it UV light.
