The waves in Morro Bay are glowing blue. And no, it isn’t a toxic spill.
The eerie blue-green color is caused by the presence of bioluminescent phytoplankton called Lingulodinium polyedrum.
These tiny organisms give off a light in response to stress, such as a wave crashing or any other movement in the water, according to Mother Nature Network.
The result is a weird blueish-green light that you can see with the naked eye at night. Photographers using long exposure techniques have captured the incredible scene just north of Morro Rock.
Never miss a local story.
According to KSBY, photographer Adam Meinke could also see a dull blue glow from shore this week. The glow was strongest at low tide and very late at night.
Here are a few other shots of the blue lights.
