gurnard fish

Gurnard fish are bottom‑dwelling, armor‑headed sea fish known for their firm white flesh, “walking” pectoral fins, and, in some species, dramatic wing‑like fins that they can flare open.

What is a gurnard fish?

Gurnards (also called sea robins) are coastal, bottom‑living fish in the family Triglidae, found on sandy or gravel sea beds from shallow inshore waters down to a few hundred meters.

They have large bony heads with spines, big eyes, and modified “finger‑like” pectoral fin rays they use to probe the seabed and even “crawl” along it while searching for food.

Species and appearance

Several species are called gurnard, including red, grey, tub gurnard in European waters and a New Zealand species (Chelidonichthys kumu), plus the related flying gurnard with very large wing‑like fins.

Many have reddish to brownish bodies with bright blue or green highlights on their fins, and flying gurnards can suddenly spread phosphorescent blue‑tipped “wings,” which has made them popular in online photos and forum posts.

Habitat and behavior

Gurnards live on continental shelf grounds, typically between about 20–250 m depth in the northeast Atlantic and around New Zealand on sandy shell or mixed seabeds to about 180 m.

They are opportunistic predators that hunt small fish, bivalves, crustaceans, worms, and other bottom invertebrates, often using those separated pectoral “fingers” to detect and flush out prey.

Sound‑making and “walking”

Many gurnards can produce grunting or growling sounds using muscles attached to the swim bladder, which is thought to help them keep in contact with other fish, especially during spawning.

Their unusual leg‑like fin rays make them look as if they have “legs” and can walk on the seabed, a feature that frequently attracts attention and jokes in online forum discussions and viral clips.

As food and sustainability

Gurnards have lean, firm white flesh with a good texture and flavour, high in protein, vitamin rich, and low in fat, and they hold together well in soups, stews, and pan‑frying.

They were long treated as low‑value bycatch and often discarded, but in places like the UK and New Zealand they are now promoted as a sustainable choice, with growing demand supported by stock assessments and by chefs featuring them on menus.
