Sea robins, also known as gurnard, are bottom-feeding scorpaeniform fishes 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 of up 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 the body. Another distinctive feature is the presence of a "drumming muscle" that makes sounds by beating against the swim bladder.[1] When caught, they make a croaking noise similar to a frog.

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 pelvic fins have been thought to let the fish "walk" on the bottom, but are really used to stir up food. The first three rays of the pectoral fins are membrane free and used for chemoreception.

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

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

Angling

Sea robins are known as rough fish, and are often caught when fishing for more desirable fish, such as striped bass. They can be caught by casting meat near the seafloor, where they actively feed. Mackerel is believed to be the most efficient meat for catching sea robins, but bunker and other fish meat can also be used successfully as bait. Sea robins can also be caught by lure fishing if lured near the substrate. These fish may put up a fight when attempted to be caught. Many anglers will leave these fish to die on land out of dislike, which is why it is the featured species at pop culture websites like garbagefish.com.

Species

There are 114 species in eight genera:
