The king mackerel, Scomberomorus cavalla, is a powerful, fast-swimming fish found in the Atlantic Ocean. It boasts a streamlined body, a silvery appearance, and a distinctive lateral line that curves downward. Known for its predatory skills, it feeds on smaller fish and plays a crucial role in marine ecosystems.

Scomberomorus cavalla, commonly known as the king mackerel, is native to the western Atlantic Ocean. It is found from Massachusetts in the United States down the eastern seaboard, through the Gulf of Mexico, and along the Caribbean Sea to Brazil.

King mackerel inhabit marine environments and are typically found in coastal waters. They prefer warm waters ranging from 20°C to 29°C (68°F to 84°F) and are often found near the surface, especially over reefs, wrecks, or other structures that provide shelter and feeding opportunities. They tend to stay in waters less than 200 meters deep but can occasionally be found deeper.

Scomberomorus cavalla is a pelagic predator, occupying the mid-level of the food chain. It feeds primarily on small fish such as menhaden, jacks, and sardines, as well as squid and shrimp. The species plays a significant role in marine ecosystems as both predator and prey, supporting various larger marine animals, including sharks and larger predatory fish.
