Description
The cod is the type fish of the family Gadidae. The 1911 Encyclopaedia Britannica spends its head on where that family sits in science. Gadids have no spines in their fins. Old schemes grouped them with herrings and pike as soft finned fish. Their closed air bladder set them apart from that group. They were then placed near the flat fishes in a suborder of their own.
Later study showed flat fishes are not their kin at all. Flat fishes turn out to be near the John Dories instead. The suborder is kept for the Gadids and two allied families. The entry then defines that suborder bone by bone. Marks include fins without spines and a tail fin of a set build. The tail is held to be a later form in the line. The fish's own habits come later in the full text.
