Mackerel and include the butterfly mackerel, a species of primitive mackerel. Mackerel are strong swimmers. Atlantic mackerel can swim at a sustained speed of 0.98 metres/sec with a burst speed of 5.5 m/s, while chub mackerel can swim at a sustained speed of 0.92 m/s with a burst speed of 2.25 m/s. Most mackerel species have restricted distribution ranges. Three species of jack mackerels are found in coastal waters around New Zealand: the Australasian, Chilean and Pacific jack mackerels.
