Triglidae, commonly known as sea robins or gurnard, are a family of bottom-feeding scorpaeniform fish. They get their name (sea robin) from the orange ventral surface of the species in the Western Atlantic (Prionotus carolinus) and from large pectoral fins, which, when swimming, open and close like a bird's wings in flight. The large surface area of the fin also permits the fish to glide short distances above the water surface, much like a flying fish.
