Sardines Group Together In Large School | Awesome Nature Photographs. Hovden Cannery in Monterey, Calif., once took Pacific sardines by the thousands and put the silvery fish into tins to be eaten. But the cannery is long gone, and (live) sardines serve a different purpose at the Monterey Bay Aquarium, where the cannery once stood: amazing curious visitors.
This photograph shows a large school of sardines in the aquarium's "Open Sea" exhibit. Sardines school to avoid predators, said curator Paul Clarkson. "It's a safety-in-numbers gambit," he told OurAmazingPlanet. "This makes it harder for a predator to target any single individual. " This classic schooling behavior is seen in a wide variety of fish. The presence of predators like mahi-mahi, bluefin tuna and hammerhead sharks in the same exhibit keep the fish from getting complacent, Clarkson said. Sardines were heavily fished in the first half of the 20th century, according to the aquarium, and overfishing led their populations to collapse. The Known Universe.
