Each year, little blue creatures wash up along the California coast. They’re about two and a half inches across, blue, and shaped kind of like pringles. Sometimes they’re beached by the millions. They’re called velella velella.

Take a trip to the bottom of San Francisco Bay, and you’d find a lot of critters that aren’t supposed to be here at all. Hundreds of tiny, exotic organisms now live there, too.

“It’s unfortunately on the rarer side to find those things that should be here,” says Chris Brown, a biologist with the Smithsonian Environmental Research Center, based in Marin. His lab works to locate and identify foreign marine life. Brown says the Bay is like an underwater zoo, with species from all over the world.
