Biofluorescence in the Platypus

Just when you thought the platypus couldn’t get any stranger...

A wonderful bit on the Platypus from a recent conference: [doi: 10.3897/biss.4.59089](https://biss.pensoft.net/articles.php?id=59089&journal_name=...). Video of the talk will be here if not already: https://www.youtube.com/channel/UC3k926cEitgTHn0ib9FvJHA/vid...

At what point does it become obvious that someone is playing a joke on us?

The didn't characterize the species that causes fluorescence, but it's likely bile dyes that probably serve for UV protection.

The creators of Perry the Platypus have been vindicated.
