Sea robins, also known as gurnard, are bottom-feeding scorpaeniform fish in the family Triglidae. They get their name from their large pectoral fins, which, when swimming, open and close like a bird's wings in flight.

They are bottom-dwelling fish, living at depths to 200 m (660 ft). Most species are around 30 to 40 cm (12 to 16 in) in length. They have an unusually solid skull, and many species also possess armored plates on their bodies. Another distinctive feature is the presence of a "drumming muscle" that makes sounds by beating against the swim bladder.[2] When caught, they make a croaking noise similar to a frog, which has given them the onomatopoeic name gurnard.[3]

Sea robins have six spiny "legs", three on each side. These legs are actually flexible spines that were once part of the pectoral fin. Over time, the spines separated themselves from the rest of the fin, developing into feeler-like "forelegs". The pectoral fins have been thought to let the fish "walk" on the bottom, but are really used to stir up food.[citation needed] The first three rays of the pectoral fins are membrane-free and used for chemoreception.[citation needed]

Sea robins have sharp spines on their gill plates and dorsal fins that inject a mild poison, causing slight pain for two to three days.

As food[edit]

Sea robin flesh is described as firm and tender when cooked. The fish serves as an adequate replacement to rascasse, or scorpionfish, in bouillabaisse.[citation needed]


Sea robins can be caught by dropping a variety of baits and lures to the seafloor, where they actively feed. Mackerel is believed to be the most efficient bait for catching sea robins, but bunker and other fish meat can also be used successfully depending on location. Sea robins can also be caught by lure fishing if lured near the substrate. They are often considered to be rough fish, caught when fishing for more desirable fish such as striped bass.[citation needed]
