Grunion Run San Diego

Experience a Remarkable Grunion Run with Birch Aquarium at Scripps
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 to early June, 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.
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, ages 6+.
