Now this is cool!
An aggregation of anchovy amassed near Scripps Pier at Scripps Institution of Oceanography, UC San Diego in La Jolla, Calif. on July 8, 2014.
This is rather a rare sight as anchovies tend to enjoy the cooler waters of the ocean, so hugging the shoreline like this is out of the norm.
The school forms walls 15 feet high as they swim together, divers and ocean lovers are seen checking them out in the clear waters.
