Similar Species
Spanish mackerel are similar in appearance to small King mackerel (Scomberomorus cavalla) and Cero mackerel (Scomberomorus regalis). All three are very similar in shape and coloration. They may be distinguished as follows:
The lateral line on Spanish and Cero mackerel slopes gradually from the top edge of the gill to the tail. In contrast that of the king mackerel takes an abrupt drop at mid-body.
The first (spiny) dorsal on Spanish and Cero mackerel has a prominent black patch. The King mackerel has none. As all three species normally keep the first dorsal folded back in a body groove, this difference is not immediately evident.
Spanish mackerel have prominent yellow spots on the flanks at all sizes. In addition to such spots, Cero mackerel have one or more yellow stripes along the centerline. Young King mackerel have similar, but slightly smaller spots; these fade away on individuals weighing over 10 pounds (4.5 kg), but they may still be seen as spots of slightly darker green on the upper back from some angles of view.
World wide there are many members of this genus quite similar to one or another of these three species. In particular, off Mexico, Atlantic Spanish mackerel may be confused with Serra Spanish mackerel (Scomberomorus brasiliensis) which may appear in the same area.

Famous quotes containing the words similar and/or species:
“A work of art is an abstract or epitome of the world. It is the result or expression of nature, in miniature. For, although the works of nature are innumerable and all different, the result or the expression of them all is similar and single.”
—Ralph Waldo Emerson (1803–1882)
“A man can go from being a lover to being a stranger in three moves flat ... but a woman under the guise of friendship will engage in acts of duplicity which come to light very much later. There are different species of self-justification.”
