California Lab Releases 20,000 Endangered Sea Snails

In a bright marine lab north of San Francisco, scientists are playing matchmaker to save a species that was nearly lost forever.

The white abalone, a large sea snail with an iridescent shell, once thrived along California's coast. By 2001, overfishing had wiped out 99% of the population, leaving just 2,000 individuals scattered across the ocean floor. Left alone, they would have gone extinct within a decade.

Instead, something remarkable happened. The white abalone became the first marine invertebrate listed as endangered, and scientists at UC Davis's Bodega Marine Laboratory got to work saving them.

On spawning days, the lab transforms into something between a science facility and a romantic getaway. Director Alyssa Frederick and her team place healthy abalone into buckets filled with a "love potion" of hydrogen peroxide that encourages breeding. They dim the lights, switch on red bulbs, and sometimes play Marvin Gaye.

"It's totally unscientific, but it makes us feel like we're doing something," Frederick laughs. The mood setting may not be proven, but the results speak for themselves.

Since opening in 2011, the Bodega Bay lab has released over 20,000 white abalone into their native waters. That's a tenfold increase from the devastating low point just two decades ago. The single room facility houses 110 abalone ranging from newborns to 25-year-old adults.

The program nearly ended last year when proposed federal cuts threatened to eliminate its funding. Anonymous donors stepped in with emergency support, and federal funding was later restored for 2026. The close call taught Frederick an important lesson about diversifying financial support to protect the species long term.

The Ripple Effect

The white abalone recovery shows what's possible when scientists refuse to give up on endangered species. The breeding program has created a model for saving other struggling marine invertebrates, proving that even animals on the very edge of extinction can bounce back with dedicated care.

Frederick describes the snails as "derpy" creatures with shy, curious personalities. When they feel safe, they reveal tiny faces with tentacles and brown heads that peek out from their shells. These strange, ancient animals are getting a second chance at survival.

The lab's success demonstrates that conservation works, even when the odds seem impossible. From 2,000 individuals to over 20,000 released back into the ocean, the white abalone is writing a comeback story that gives hope for countless other species teetering on the brink.
