Morphological traits uniting the flying gurnards (Dactylopteridae) and the Syngnathiformes have long been noted. Dactyloptena is a genus of flying gurnards native to the Indian and Pacific oceans. As with other sea robins, grey gurnards produce sounds. Growling in gurnards gives an advantage when there is limited food resources. Smallscaled gurnards ("Chelidonichthys") is a fish genus in the family Triglidae. Grey gurnards are of commercial importance as a food. In May both Gurnards flew as landplanes from Lympne, where Shorts maintained a base. Gurnards are very distinctive bottom-living fish with large heads and eyes.
