Friendly reminder that the platypus is a semi-aquatic, venomous mammal that lays eggs and can sense electricity. They’re also biofluorescent, so they glow blue under UV light:
Ah, but “visible light” as a category is human-centric in that it’s based only on which wavelengths of electromagnetic radiation our eyes can detect or “see”. Other species can see more or different wavelengths, such as UV.

Every time I hear a new platypus fact I am convinced the whole animal is a hoax.
They also swallow rocks to digest food.
Lacking teats, they sweat milk to feed their babies. And their left ovary is non-functional.
This was how early mammals fed their young, nipples evolved later on. I’m no specialist but I suppose that’s when platypuses branched out
Really? Awesome. You made my day.
How do I unsubscribe from Platypus Facts?
Opossums also glow under UV.
That tracks. I wonder why some animals do that and others don’t. It’s not like there’s much natural uv in any situation lacking visible light
