Peristediidae

Peristediinae, the armored sea robins or armoured gurnards, is a subfamily of ray-finned fishes belonging to the sea robin family Triglidae in the order Perciformes. They are found in the deep water in the tropical and warm temperate of the world's oceans.

==Taxonomy== Peristediidae was first proposed as a family in 1883 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert. The 5th edition of Fishes of the World classified the family within the Platycephaloidei, which is a suborder of the order Scorpaeniformes. More recent authorities differ and do not consider the Scorpaeniformes to be a valid order because the Perciformes is not monophyletic without the taxa within the Scorpaeniformes being included within it. These authorities consider the Peristediidae to belong to the suborder Triglioidei, along with the family Triglidae, within the Perciformes. Presently, ''Eschmeyer's Catalog of Fishes includes it within the Triglidae as the subfamily Peristediinae, and place the Triglidae in the suborder Scorpaenoidei.
