Six North American bat species glow green under UV light, a first for the region, likely inherited genetically.
Researchers at the University of Georgia have discovered that six North American bat species emit a greenish glow under ultraviolet light, marking the first confirmed case of photoluminescence in bats in the region.
The glow, observed in wings and hind limbs, is consistent across sexes and species and likely genetic, inherited from a common ancestor.
While the evolutionary purpose remains unknown, scientists speculate it may have once aided communication, though it may now be an evolutionary remnant.
The finding, based on 60 specimens, opens new questions about bat behavior and adaptation, with further research needed to determine any current ecological role.
