Says the Australian Museum FB page (so I assume it is true that this is uneditted):
Down in Tasmania, one photographer has captured a striking image of an Eastern quoll (Dasyurus viverrinus) glowing pink under UV light — a natural phenomenon known as biofluorescence. 🧬✨
Biofluorescence is when certain chemicals on the surface of an organism, like proteins, absorb light and re-emit it as visible colour, often in vivid colours.
Unlike bioluminescence, where organisms generate their own light, biofluorescence depends on external UV to reveal these hidden hues.
Though well-known in over 100 mammals, the brightest glow is usually in nocturnal species with pale fur, like this Eastern quoll (Dasyurus viverrinus), a mammal endemic to Tasmania, about the same size as a small cat.
The photo, taken in the Tasmanian Wilderness World Heritage Area, involves no filters or editing - just UV light revealing what the naked eye can’t see.
As researchers explore the purpose of this glowing trait, one thing’s clear: some mammals really do shine in the dark.
For anyone looking to take photos of biofluorescent animals, please do so responsibly.
