Blue Marlin Facts, Habitat, and Conservation | Marine Species Guide #208896 (License: Personal Use)

This illustration depicts the blue marlin (Makaira nigricans), one of the largest and fastest predatory fish in the world, known for its striking cobalt-blue dorsal surface fading to silvery-white ventrally. Its elongated upper jaw forms a spear-like bill used for slashing prey, while the high, rigid dorsal fin aids in stability during high-speed pursuits. The species inhabits tropical and subtropical oceans globally and is prized in sport fishing but faces threats from overfishing and bycatch.
