Experience the Remarkable Grunion Run with Birch Aquarium at Scripps

Witness the amazing mating ritual with aquarium naturalists

Scripps Institution of Oceanography / University of California, San Diego

Join Birch Aquarium at Scripps Institution of Oceanography, UC San Diego, for a must-see ocean adventure. From April 16 through the end of May, observe the mysterious grunion spawn on the beaches of La Jolla.

Grunion Run programs feature a rare opportunity to witness grunion eggs hatch before your eyes.


On certain spring nights following high tides, hundreds of the small, silvery fish ride the waves onto shore for this remarkable mating ritual. While on the beach, female grunion bury themselves in the sand to lay eggs, while males wrap themselves protectively around the females to fertilize their eggs. Both catch a wave to return to sea.

Birch Aquarium at Scripps naturalists will guide participants through an unforgettable night, starting with a presentation on grunion, followed by a rare opportunity to witness grunion eggs hatch before their eyes. The unique experience continues with a moonlight beach exploration. Please bring a flashlight and warm jacket. The program is $12 per person.
