Recent evidence suggests that ultraviolet fluorescence is more widespread among mammals than previously thought. For instance, the presence of fluorescence has been observed in both live and museum specimens of several species of pocket gophers (Family Geomyidae). We examined a live specimen of Baird's pocket gopher (Geomys breviceps) as well as museum specimens from four species of geomyids for evidence of ultraviolet fluorescence. Coverage and intensity of fluorescence was greatest in the live specimen. All museum specimens showed evidence of fluorescence although coverage and intensity decreased with specimen age. Additional research is needed to determine the source and ecological significance of ultraviolet fluorescence in pocket gophers.
