Anemone Tentacles in Motion, Ultraviolet Light, Tongue Point, Washington

Viewed under ultraviolet light, a long exposure captures the motion of giant green anemone (Anthopleura xanthogrammica) tentacles 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.
