Coloration varies among races — mostly as function of extent of intrusion of dark dorsal cape over lighter lateral area and extension of white sides. Beak extremely long and slim — usually dark above, white below. Tip of snout and lips distinctly black. Dorsal fin ranges from tall and triangular, even canting forward, to moderately falcate. Often jumps and spins on longitudinal axis. Flees from vessels in eastern tropical Pacific tuna fishing areas, rides bow wave in other areas.
