Scientists find fire salamanders glow blue-green under UV light from secretions
Under ultraviolet light, adult fire salamanders reveal a captivating blue-green fluorescence generated by their skin secretions, lasting for several hours. This striking luminescence is mainly concentrated in areas rich in glands, especially along their flanks and underside. Researchers propose that this unique trait could serve functions in communication or as a warning signal, enhancing our understanding of the fire salamander's biology.
