Atlantic Mackerel Scomber scombrus
A streamlined, fast-swimming fish that is found in dense shoals that move as one. Mackerel migrate to shallower inshore waters in the summer and feed on zooplankton and small fish, particularly sand eels. They are identifiable by the beautiful tiger-like markings on their backs.
