The northern searobin is a species of fish native to the continent of North America, mainly the eastern coast of the United States, from New York to the Cape Hatteras, and from the Gulf of Mexico to Nova Scotia. It is also known as gurnard or the common sea robin.
The 'searobin' name partially comes from the wing-like pectoral fins that make it look like a bird.
The northern searobin habitat is the sandy bottoms of the continental shelf of the continent. This bony fish is also known to make a croaking call using its swim bladder and has a black spot on the initial dorsal fin.
The northern searobin reproduces via external fertilization and is known to give out a staccato-like call in the mating season.
This species is often caught accidentally by recreational and commercial fishermen. Its eggs are sometimes used as a caviar substitute and the bony fish itself is eaten with food like soups and stews.
