The numerous species live chiefly in the northern seas, some of them descending to great depths. The resemblance of these fishes to some of the Blennioid group is very strongly marked, but these likenesses seem analogical only and not indicative of true affinity. The codfishes probably represent an early offshoot from the ancestors of the spiny-rayed fishes, and their line of evolution is unknown, possibly from Ganoid types. Among recent fishes there is nothing structurally nearer than the Nototheniida: and BrctulidcB, but the line of descent must branch off much farther back than either of these. For the present, therefore, we may re- gard the codfishes and their allies {Anacanthini) as a distinct order. The Codfishes: Gadidae.—The chief family is that of the GadidcB, or codfishes. These are characterized by a general resemblance to the common codfish, Gadiis callarias. This is one of the best. 653.—Codfish, Gadus callarias L. Eastport, Me. known of fishes, found everywhere on the shores of the North Atlantic, and the subject of economic fisheries of the greatest importance. Its flesh is white, flaky, rather tasteless, but takes salt readily, and is peculiarly well adapted for drying. The average size of the codfish is about ten pounds, but Captain.
