Marine fishes exhibit exceptional variation in biofluorescent emission spectra journals.plos.org/plosone/arti & Repeated and widespread #evolution of #biofluorescence in marine fishes nature.com/articles/s41467-025 by Emily Carr et al.

"#fish that live in or around #CoralReefs evolve biofluorescence at about 10 times the rate of non-reef species, with an increase following the Cretaceous-Paleogene #extinction"

A recent study reveals that 37 out of 45 birds-of-paradise species exhibit biofluorescence, absorbing UV or blue light and emitting it as vibrant colors. This phenomenon enhances males' courtship displays and may serve as camouflage for females. Nature's wonders never cease to amaze!

The Guardian · Many birds-of-paradise species emit light through their plumage, study findsBy Nicola Davis

Study Finds That #BirdsOfParadise Are Biofluorescent amnh.org/about/press-center/bi paper: royalsocietypublishing.org/doi

"an organism absorbs light, transforms it, and emits it as a different color... This phenomenon is especially prominent in males, focused on their bright plumage and skin in areas that are highlighted during displays: the inner mouth and bill, feet, and feathers on the head, neck, and belly... pigments in the #birds’ eyes align with the #fluorescence peaks"

"An eerie glow has been emanating from #Wales' #forests and #rockpools for the country's annual dark skies week.

"David Atthowe, a nature guide from Norwich, was invited to shine his ultraviolet (UV) torches on some of the best nature spots in Pembrokeshire and Monmouthshire.

"His photos of temperate rain forest in Wales reveal shapes, structures and colours that rival a coral reef.

"'It is hidden from our human senses, waiting to be discovered,' he said."

A survey of hundreds of frogs in South America shows that far more frogs are biofluorescent than previously thought. Could it be that the ghostly colors may have a role in the way they communicate with members of the same species? Science News dives in.
