No they are not green onions.
Last night, after getting ready to go home, someone made the announcement: “So we’re going to see some silver fish spawn on the ocean under the night of the full moon.”
“Uh! Sign me up!” Seeing nature in its quirkiest and coolest is right up my alley. I went back home to grab a jacket and then met up and rode south with them to Cabrillo beach.
Grunion are a southern California phenomenon. They come every year with the tide and spawn on the beach. The female will ride the wave in and as many 8 males may accompany her. If there are no males, the female will just the ride the wave back in the ocean and try again. When she does come ashore, she digs a hole with her tale and the male comes up alongside her and drops his milt. Then they wiggle back and forth to get back into the ocean.
The eggs get fertilized and hatch after about 10 days. The aquarium next to the beach gives demonstrations on how easy it is to hatch the eggs. What they’ll do is get some fertilized eggs in a jar, add in some sea water, and shake vigoriously (to mimic the waves). The little fish will hatch from that motion and voila! Easy peezy.
Last night I imagined a magical beach full of flippy floppy silver fish gleaming under the glow of the full moon. What actually happened was a bunch of people with headlights on looking intently into the dark sea, getting really excited when they saw a rock (in our defense, it looked like a fish, really!)
