General Description
The body of the King Mackerel is iron-gray along the back, and silvery on the sides and belly.

Juvenile King Mackerel and adult Spanish Mackerel can be easily confused. Juvenile King Mackerel will sometimes have the yellowish spots much the same as mature Spanish mackerel. A juvenile King Mackerel’s lateral line dips significantly compared to a Spanish Mackerel. The dorsal fin of a juvenile King will be a much lighter color, more of a gray or white color than the Spanish, whose dorsal fin will be black or very dark in color.
