[CA] The grunion are running


Recommended Posts

The silvery fish are making their way onto southern California beaches. The Times is on it:

 

 

Every year, thousands of little fish ride waves onto Southern California’s beaches at night to lay and fertilize eggs. High up in the sand, they squirm, wriggle and wrap around one another. As they dance beneath the moonlight, the beach transforms into a twinkling tapestry of spawning silver bodies. It’s known as the grunion run, and within a few hours, the show is over.

This spectacular reproductive event occurs twice a month on nights after new and full moons, when tides are at their highest. The show, which plays out on West Coast beaches from Baja California, Mexico, up to San Francisco Bay, peaks between April and May, but can last from late February through August. With Tuesday’s full moon just past, now is the perfect time for a grunion run, if you happen to be in the area.
