Polyamblyodon is a genus of marin ray-finned fishes belonging to the family Sparidae, which includes the seabreams and porgies. The fishes in this genus are found in the Western Indian Ocean.
Polyamblyodon was first proposed as a genus in 1935 by the English ichthyologist John Roxborough Norman with Pachymetopon germanum as its type species.[1] P. germanum was first formally described in 1935 by the South African zoologist Keppel Harcourt Barnard with its type locality given as Durban in KwaZulu-Natal.[2] This genus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.[3] Some authorities classify this genus in the subfamily Boopsinae,[4] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.[3]
Etymology
Polyambylodon is a compound of poly, meaning "many" with amblys, meaning "blunt", and odon, meaning "tooth", a reference to what Normnan, referring to the German seabream, described as “outer row of strong, curved, compressed chisel-like teeth in each jaw , behind which is a broad band composed of 6 or 7 rows of small rounded molariform teeth”.[5]
Species
Polyamblyodon contains two recognised species:[6]
- Polyamblyodon germanum (Barnard, 1934) (German seabream)
- Polyamblyodon gibbosum (Pellegrin, 1914) (Knife-back seabream)
