Ga*noi"de*i, n. pl. Etym: [NL. See Ganoid.] (Zoöl.)
Definition: One of the subclasses of fishes. They have an arterial cone and
bulb, spiral intestinal valve, and the optic nerves united by a
chiasma. Many of the species are covered with bony plates, or with
ganoid scales; others have cycloid scales.
Note: They were numerous, and some of them of large size, in early
geological periods; but they are represented by comparatively few
living species, most of which inhabit fresh waters, as the bowfin,
gar pike, bichir, Ceratodus, paddle fish, and sturgeon.
