Gurnards are also called Sea Robins, are bottom-feeding scorpaeniform fishes in the family Triglidae. They were named as such because their wing-like pectoral fins open and close like a bird's wings in flight when swimming.
Gurnards (Chelidonichthys kumu) are also known as "Kumu-kumu" by the Maoris, they are easily recognised by its wing-like side fins and finger-like feelers adjacent to these fins. These "fingers" are used to search for food at the sea bottom. The gurnard has an unusual solid skull and some species have armour plates throughout its whole body. They grow up to 20 in. in length, but the usual size is 13–15 in. They are considered good-eating fish and can be caught in most parts of New Zealand.
