Delphinus delphis feed on small fish as well as squid and octopus. Small fish include young herring, pilchard, anchovies, nocturnal hake, sardines, small bonito, as well as sauries. Individual dolphins eat up to 18 to 20 pounds of fish per day. Groups of common dolphins all feed at the same time during the night or day. They are sometimes joined by bands of bottlenose or white-sided dolphins. These feeding forays can last up to an hour. During these, each dolphin rushes to the center of the school the group has been pursuing and tries to seize as many fish as possible, which it swallows whole. Common dolphins have also been known to dive below schools and drive them to the surface. They push their prey completely out of the water and catch them in midair.
