Ephippidae

Ephippidae is a family of percomorph fishes in the suborder Moronoidei of the order Acanthuriformes. These fishes, commonly known as spadefishes, are found in the tropical and temperate oceans of the world, except for the central Pacific.

== Taxonomy == Ephippidae was first proposed as a family in 1859 by the Dutch herpetologist and ichthyologist Pieter Bleeker. The 5th edition of the Fishes of the World classifies this family in the order Moroniformes with the Moronidae and Drepaneidae. Other authorities place this family alongside the Drepaneidae in the order Ephippiformes with the Moronidae classified as incertae sedis in the series Eupercaria. Other authorities classify all three families in the Moroniformes sensu Fishes of the World in the Acanthuriformes.
