THE SPANISH MACKEREL (_Scomberomorus maculatus_) The Spanish mackerel was first described by Dr. Mitchill, in 1815, from the vicinity of New York. He named it _maculatus_, or "spotted," owing to the large bronze spots on its sides. It is common to the southern portions of the Atlantic and Pacific coasts and the Gulf of Mexico, ranging in summer as far north as Cape Cod, and is one of the trimmest and most graceful fishes known, as well as one of the most beautiful both in form and coloration. It is especially adapted for rapid and sustained motion. Its long, graceful, and elliptical body is four times its depth. The head is as long as the depth of the body, with a large mouth, and sharp, lancet-shaped teeth in both jaws. It has two dorsal fins; the second dorsal and anal fins are nearly opposite each other, are similar in outline, and are each followed by nine detached finlets; the caudal fin is widely forked, the lobes being long and pointed or crescent-shaped. Its color is silvery, bluish or greenish above, paling to white on the belly, with iridescent reflections; the sides are dotted with some thirty bronze or golden spots, a fourth of an inch or more in diameter; the first dorsal fin is dark in front, whitish behind; the second dorsal is yellowish; the anal fin is pale; the pectoral fin is yellow, bordered with black; the caudal fin is dusky. The Spanish mackerel is gregarious and migratory, swimming in large schools, and feeding at the surface on pilchards, anchovies, and sardines in Florida, and on silversides and menhaden in northern waters. When feeding, the schools are constantly leaping above the surface, and the flashing of their silvery forms in the bright sunlight is a beautiful and inspiriting sight, enhanced by the flocks of gulls and terns whirling and darting above the schools, eager for such stray morsels and fragments as they are able to seize. In the Gulf of Mexico it often feeds in company with the salt-water trout, and in northern waters with the bluefish and weakfish.
