Fun Science FRIEDay – Dude, I’m Glowing!

Happy Fun Science FRIEDay! After a brief hiatus, due to life, hoping this installment represents the regular…err, semi-regular, occurrence of FSF.

So this hit the interwebs pretty big earlier this week, the first documented reptile to glow. That honor belongs to the Hawksbill a sea turtle, observed first by  David Gruber, of City University of New York.

Lets get one thing out of the way before we delve into the glowing version of Crusher (for my finding Nemo aficionados). The sea turtle is not glowing, its fluorescing… there is a difference. In the ocean lots of organisms fluoresce at longer wavelengths (green, yellow, red) in response to shorter wavelengths (UV, blue, violet). It is a typical property of many biological materials and is noticeable if viewed through restrictive long pass filters, as is the case here.

That being said, documenting a sea turtle fluorescing is still pretty freaking cool! Like many scientific discoveries this was totally by happenstance. David was in the Solomon Islands to film biofluorescence in small sharks and coral reefs. And during his observations of sharks and corals glowing Crusher just swims by like, “Dude, I’m all glowing and stuff.”

Checkout the awesome video of it below, and Happy FSF!
