2 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Ganoidei \Ga*noi"de*i\, n. pl [NL. See {Ganoid}.] (Zo["o]l.) 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. From WordNet r 1.6 [wn]: Ganoidei n : a group of mostly extinct primitive bony fishes characterized by armor-like bony scales [syn: {Ganoidei}, {order Ganoidei}]
