    • n gasterosteus The typical genus of the family Gasterosteidæ, by some extended to include all the species of that family, but by others restricted to the short species with pelvic bones forming a triangular plate, and two dorsal spines, as G. aculeatus: so called from the extension of the pubic bones along the ventral aspect of the fish, making the belly bony. See stickleback.
