Taxonomy and history

The genus Sphyrion was erected by French zoologist Georges Cuvier in volume three of the second edition of Le Règne Animal, published in 1830.[1][2] The name Sphyrion appears to be derived from the Greek word σφυρίον, meaning "little hammer".[3][4]

The type species, first described in 1824 by Jean René Constant Quoy and Joseph Paul Gaimard, was provided with both a common name ("Chondracanthe lisse") and a binomial name (Chondracanthus levis).[5] When erecting the genus Sphyrion, Cuvier referred to this species  now recognised as Sphyrion laevigatum  using the common name "Chondracanthe lisse".[2][3][4][5]

Three species are currently recognised.[1][6]
