Giant Green Anemone Under Ultraviolet Light, Tongue Point, Washington

A giant green anemone (Anthopleura xanthogrammica) seems to glow when exposed to ultraviolet light at low tide on Tongue Point in the Salt Creek Recreation Area near Port Angeles, Washington. The vibrant colors are the result of fluorescence, a type of photoluminescence, in which certain chemicals absorb light that is invisible to human eyes and emit some of it at a different wavelength that we can see. This scene was captured under black light.
