Who ordered the anchovies?
That's what beach-goers may be asking after a huge swarm of the oily fish descended on the shallow waters of La Jolla Shores, California, this week.
"It is rare to see so many anchovy abutting the surf zone," said Professor Dave Checkley of the Scripps Institution of Oceanography (SIO). "More usually, schools are seen hundreds of yards to many miles offshore." The surf zone is the area in which waves break on shore and humans normally swim.
