What Divers Should Know About Flying Gurnard

The flying gurnard (Dactylopterus volitans), also known as the helmet gurnard, is a distinctive bottom-dwelling fish inhabiting tropical to warm temperate waters on both sides of the Atlantic Ocean. Its extensive distribution spans from Massachusetts, including the Caribbean Sea and Gulf of Mexico, all the way to Argentina on the American side. Across the Atlantic, populations range from the English Channel down to Angola, encompassing the Mediterranean Sea. This unique creature is the only species within its genus, Dactylopterus, making it a truly monotypic encounter.

When encountered, this striking fish can measure up to 50 cm (20 in) in length and weigh 1.8 kg (4.0 lb). Its coloration is quite variable, often displaying shades of brown or green accented with reddish or yellowish patches, complemented by large eyes. Observing a flying gurnard often reveals its active feeding strategy; it is a predator of small fish, bivalves, and crustaceans. Divers may even witness it employing its robust pectoral fins to expertly dig into the sediment, unearthing hidden prey with impressive precision.
