From late March through May, folks can observe the mysterious grunion spawn on the beaches of La Jolla.
On certain spring nights following high tides, hundreds of the small, silvery fish ride the waves onto shore for this remarkable mating ritual, which happens only in Southern California.
While on the beach, female grunion bury themselves half-way in the sand to lay eggs, while males wrap themselves 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 an interactive 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 to witness the grunion run, nature willing. Please bring a flashlight and warm jacket.
The program is $14 per person, ages 6+. Ages 6-13 must attend with a paid adult.
