Fish Out of Water: Birch Aquarium at Scripps to host grunion-run activities in La Jolla
On certain spring nights following high tides, hundreds of the small silvery fish called grunions ride the waves onto shore for a remarkable mating ritual, which happens only in Southern California from March through mid-June.
While on the beach, female grunion bury themselves halfway in the sand to lay eggs, while males wrap themselves around the females to fertilize their eggs. Then, both catch a wave to return to sea.
Birch Aquarium at Scripps naturalists will guide participants through these unforgettable nights, starting with an interactive presentation on grunion, followed by a rare opportunity to witness grunion eggs hatch before their eyes. The fun continues with a moonlight beach exploration in La Jolla to witness the grunion run, nature willing. Bring a flashlight and warm jacket.
Each event meets at Sumner Auditorium at Scripps Institution of Oceanography, 8622 Kennel Way, La Jolla. The cost is $14 for members, $16 for others. Ages 6-13 must attend with a paid adult. Advance reservations required by calling (858) 534-7336 or visit aquarium.ucsd.edu
