What is causing the waves in California to glow?

What is causing the waves in California to glow?
It looks like something from the movie "Avatar": ocean waters that light up like neon glow sticks when they splash. Beaches across southern California have recently been alight with eerie, glowing waves. What could be causing such an otherworldly phenomenon? A recent report by Discovery News has provided an answer. According to marine biologist Jorge Ribas, the glowing is caused by a massive red tide, or algae bloom, of bioluminescent phytoplankton called Lingulodinium polyedrum. The microorganisms emit light in response to stress, such as when a wave crashes into the shore, a surfboard slashes through the surf, or a kayaker's paddle splashes the water. The phenomenon has been observed on a semi-regular basis since at least 1901 along the beaches around San Diego, Calif. For surfers who don't mind catching a wave in water teeming with a sludge of microorganisms, the glowing ocean offers the chance of a lifetime.

There actually AREN'T that many fish in the sea: Rivers and lakes contain 80% of Earth's species - despite covering 2% of surface By Rob Waugh Updated: 16:51 GMT, 8 February 2012 A team led by Dr John Wiens, from Stony Brook University in New York, studied the biodiversity of ray-finned fish (such as cod, pictured) which make up 96% of all fish species Contrary to popular belief, there's not a lot of fish in the sea, say researchers. There are far more species in rivers and lakes, say researchers - and the discovery could hint at previous mass extinctions long ago.

New Galaxy Map Relocates The Milky Way To A Ginormous Supercluster Called Laniakea Astronomers have long had a sense of where the Milky Way is in relation to other galaxies, but a new three-dimensional star map gives us a more nuanced look at our cosmic neighborhood. Until now, the Milky Way was believed to be one galaxy in the 2,000 that make up what's known as the Virgo "supercluster." But as the new map shows, the Milky Way's 100 billion stars are actually part of something 100 times bigger: a supercluster of galaxies astronomers have christened Laniakea, meaning "immense heavens" in the Hawaiian language. Laniakea spans some 520 million light-years across. As you might imagine, all those stars contain a lot of mass.
