Dactylopteridae
Sign in to saveThe flying gurnards are a family, Dactylopteridae, of marine fish notable for their greatly enlarged pectoral fins. As they cannot literally fly or glide in the air (like flying fish), an alternative name preferred by some authors is helmet gurnards. They have been regarded as the only family in the suborder Dactylopteroidei of the Scorpaeniformes. However, more recent molecular classifications put them in the order Syngnathiformes, in the superfamily Centriscoidea.

The flying gurnards are a family, Dactylopteridae, of marine fish notable for their greatly enlarged pectoral fins. As they cannot literally fly or glide in the air (like flying fish), an alternative name preferred by some authors is helmet gurnards. They have been regarded as the only family in the suborder Dactylopteroidei of the Scorpaeniformes. However, more recent molecular classifications put them in the order Syngnathiformes, in the superfamily Centriscoidea.
They have been observed to "walk" along sandy sea floors while looking for crustaceans, other small invertebrates and small fish by using their pelvic fins. Like the true gurnards (sea robins), to which they may be related, they possess a swim bladder with two lobes and a "drumming muscle" that can beat against the swim bladder to produce sounds. They have heavy, protective scales and the undersides of their huge pectoral fins are brightly coloured, perhaps to startle predators.
