Invertebrates Among Kelp, Ultraviolet Light, Puget Sound, Washington
Invertebrates appear to glow blue and purple as they feed among strands of kelp when exposed to ultraviolet light at low tide at the edge of Puget Sound in Des Moines, Washington. The glow is the result of phosphors that convert ultraviolet radiation, which is invisible to human eyes, into wavelengths that are visible. This scene was captured under black light.
