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 are the only family in the suborder Dactylopteroidei. Most species are in the Indo-Pacific genus Dactyloptena, but the single member of Dactylopterus is from warmer parts of the Atlantic. The adults live on the sea bottom, but many species have an extended larval stage, which floats freely in the oceans.
