Birds-of-paradise are even colorful in the dark, with feathers and body parts that glow a brilliant yellow-green under ultraviolet (UV) light, a new study found.

Science News: A comprehensive mapping of biofluorescence across 459 fish species reveals its ancient origins in eels and subsequent independent evolution over 100 t ...

The two studies also reveal that fish biofluorescence involves a larger assortment of colors than previously reported. “Researchers have known for a while that biofluorescence is quite widespread in ...

It found biofluorescence in 37 of the 45 known birds-of-paradise species and posits that the glow is important among males for hierarchy and mating displays.
