Grunion Mate On Local Beaches On Spring Nights

Posted: Updated:

Certain spring nights are hopping with wildlife all along our coast. You may have heard of the grunion run. It's a marathon of sorts, involving small fish sprinting for dry land and plenty of people armed with flashlights hoping to get in on the action.

This is the time of year when grunion come out of the water to wish their eggs farewell. It's a dramatic sight to see hundreds of little fish only about six inches long, spawning on the sand.

Thanks to naturalists at Birch Aquarium at Scripps, you can learn where to find grunion and how they lay their eggs.

"These fish only occur here in Southern California. There's another species in Mexico which hatches during the day. So at night, at full and new moon, that's when they come up when the tides are high and lay their eggs. At full moon it's like a silver sheen; you get the reflection of the moonlight and so it's an amazing sight as thousands of fish come up to the beach. Nowhere else in the world can you see a sight like that," Birch Aquarium Executive Director Nigella Hillgarth said.

Naturalists on the guided tour will also teach you how to hatch your own grunion eggs, so you can watch the baby grunion come to life.

The next naturalist-led grunion run is on Monday, June 8 from 9:30 p.m. to 11:30 p.m.
