==Genera and species== thumb|Proposed Zanclidae cladogram by Carnevale & Tyler Zanclidae has the following taxa classified within it: Genus Zanclus Cuvier, 1831 Species Zanclus cornutus (Linnaeus, 1758) (Moorish idol) Genus Massalongius Tyler and Bannikov, 2005 Species Massalongius gazolai (Massalongo, 1859) Genus Angiolinia Carnevale & Tyler, 2024 Species Angiolinia mirabilis Carnevale & Tyler, 2024 Genus Eozanclus Blot & Voruz, 1975 Species † Eozanclus brevirostris (Agassiz, 1835) ( means extinct) left|thumb|Fossil specimen of Eozanclus Eozanclus brevirostris is an extinct species in the Zanclidae family that was first discovered by Giovanni Serafino Volta in 1796. The species later received separate taxonomic status within the Zanclidae family through the description of Blot and Voruz in 1970 and 1975. Angiolinia mirabilis is another extinct Zanclid that was described by Giorgio Carnevale and James C. Tyler in 2024 based on three specimens found in Bolca, Italy. Carnevale & Tyler found that Zanclus cornutus and Angiolinia mirabilis form a derived clade distinguishable from Eozanclus brevirostris by one supernumerary spine on the first dorsal-fin pterygiophore, one uroneural in the caudal skeleton, and distally filamentous dorsal-fin spines (except the first two fins).
