China's Xiangbi'ao beach shone with a majestic sparkling glow-in-the-dark blue hue last week after a natural phenomenon called "Sea Ghosts" invaded the waters. Sea Ghost or "Sea Sparkle" is created by the growth of an algal bloom called Noctiluca scintallans, a type of single-cell animal that loves to munch on plankton. The organisms multiply when nitrogen and phosphorus from farm fertilizer run-off enters the water. Beautiful, yes - but harmful to the ecosystem. When the blooms die, they sink to the bottom of the sea where they decompose, consuming huge amounts of oxygen and killing other marine life. Check out the Sea Sparkle on China's Xiangbi'ao beach in the pictorial gallery below.
