A dark cloud undulating in the water is captured on camera by oceanography students. It’s not an oil spill, it’s alive.
An aggregation of anchovy amassed near Scripps Pier at Scripps Institution of Oceanography, UC San Diego in La Jolla, Calif. on July 8, 2014. Footage from Scripps Pier by Scripps staff and underwater by Scripps graduate students Julia Fiedler, Sean Crosby and Bonnie Ludka.
Millions of anchovies amassed off shore. The divers captured underwater footage of the school of fish. The school of small silver fish was massive. Scientists have not seen anything like it. The mass looks like a moving blob of blue black in the shallow water until the divers get close up to watch the mass behavior. It is not known why the millions of fish congregated here. The generic term “anchovy” consists of 144 species of 17 genera. This is suspected to be the Northern anchovy. NOAA – FishWatch: Northern Anchovy.
Watch additional footage of the cloud of fish and a seal disturbing the cloud here. It’s amazing.
