Greeting the Grunion

I couldn’t help but giggle as I watched the silvery fish wiggle into the sand to lay their eggs. These mesmerizing creatures are only found along the coast of southern California and northern Baja California where they lay their eggs on sandy beaches just a few months out of the year.

Growing up in Santa Barbara, my parents took us “Grunion Hunting” at East Beach. I remember the thrill of being up and out on the sand hours beyond my usual bedtime. My sister and I would catch the Grunion in our hands and then throw them back to sea, not really understanding anything about the fish except that they were our tickets to dance around barefoot in the moonlight.

It had been decades since I’d thought about Grunion-until I wrote a story for Seasons Magazine about Santa Barbara Channel Keeper, a local nonprofit that works to protect and restore the Santa Barbara Channel and watersheds.

One of Channel Keeper’s programs, in coordination with Pepperdine University, is “Grunion Greeters,” where volunteers monitor Grunion behavior on local beaches during spawning season. As soon I heard about this I called my Dad, and we volunteered to be “Citizen Scientists,” the title the program generously bestows upon participants.

After one night’s training at UCSB, I was presented with my “Citizen Scientist” tiara and a spawning schedule in a surprisingly moving ceremony. Okay, maybe I really just got a free bag and a pen, but they called us all “scientists,” which is a crowning achievement I would love to report to my college physics professor, if he were still speaking to me, and if I actually took physics in college.

So science isn’t really my academic forte, but citizen science is fun. Unlike many fish, Grunion spawn completely out of the water, so you can actually watch them lay their eggs in the sand, which looks a little like the “Shake Your Booty” dance my son used to do in preschool.

Koss did a delighted version of the “Funky Chicken” along with some excited yelps the first time he saw the Grunion, and I was right back in my own childhood mode. We were lucky to spot Grunion right away during our scheduled monitoring time, 11:20 p.m. While the Grunion can be spotted shortly after high tide on specific nights, our trainers warned us that we wouldn’t always be able to see them-although sometimes the beaches are covered with thousands of Grunion dancing on the sand. The popularity of Grunion runs in some places means that some nights there are more people lining the beaches than Grunion in the run.

That definitely wasn’t the case at Leadbetter Beach, where we did our monitoring last week. We only ran into a few other people-some more interested in human spawning than animal mating behavior-along with a couple who had happened upon some Grunion the night before and were there for an encore, and some tourists who were enchanted by these strange silvery fish. “Whoa, Dude, that was awesome. What were those things,” they asked.

“Professor” Dad and I explained that they were Grunion there to spawn. Providing human or animal predators didn’t intervene, the eggs would remain buried in the sand for their incubation time of approximately two weeks. Then the larvae would hatch and the eggs would be washed out by high waves during tides before the new and full moons.

“Radical man. And to think we just happened upon them during one of the few nights of the year they’re in Santa Barbara. Totally awesome,” was their response.

It is totally awesome, and totally fun. The last expected Grunion runs of the season are at local beaches next week, on July 8 (Wednesday) at 10:40 p.m. and July 9 (Thursday) at 11:10 p.m. I can’t wait.

Some tips for Grunion Greeters:

Nature doesn’t always follow our schedule. The scheduled times are for high tide when the runs may begin, but keep in mind that they typically occur within a two-hour period and plan accordingly.

Bring a flashlight but use it sparingly, as less light means more of a chance that the Grunion will spawn.

It can get cold at night, so wear layers and shoes that can get wet.

If you decide to catch the Grunion (Grunion Greeters discourages this) you may only use your bare hands; no nets, hooks or gear are allowed.
