Mackerel-like (Scrombodei) from a subspecies of the Perciformes, the biggest order of fish. Mackerel (Atlantic-, horse mackerel etc), tuna, swordfish and barracudas all fall among the mackerel-like fish. Globally it is a very popular fish and forms an important source of food and income for many people. Mackerel are pelagic fish that live in large schools. While swimming in large schools, mackerel-like fish confuse their predators with the silver-like brilliance from their scales. Island mackerel is the smallest with 2o cm, the largest is the bluefin tuna that can reach a size of over 5 meters.
