Acanthopagrus is a genus of marine belonging to the family Sparidae, the sea breams and porgies. The fish in this genus are found in the Indian and western Pacific Oceans.
Taxonomy
Acanthopagrus was first proposed as a monospecific genus in 1855 by the German zoologist
Wilhelm Peters, with its only species, and
type species, being
Chrysophrys vagus which Peters had described in 1852 from Sena on the
Zambezi River in Mozambqiue.
The genus
Acanthopagrus is placed in the family Sparidae within the order
Spariformes by the 5th edition of
Fishes of the World.
Some authorities classify this genus in the subfamily Sparinae,
but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.

Etymology
Acanthopagrus is a compound of acanthus, meaning "thorn" or "spine", this allusion was not explained by Peters but may be a reference to the robust spines on the dorsal fin and the enlarged second anal-fin spine of the type species, with pagrus, which is derived from phagros, an ancient Greek name for sea breams, used as far back as Aristotle's life.

Characteristics
Acanthopagrus sea breams are characterised by the possessopn of a number of pairs of large, peg-shaped canines in the front of the jaw, an outer row of shorter canines along each side of the jaws and a few inner rows of rounded molar-like teeth at the rear of the jaws. The molar-like teeth become slightly larger towards the rear of each jaw. The dorsal fin is supported by between 12 and 15, infrequently 10 or 11, segmented rays and the anal fin is supported by 8 to 10 segmented rays. The second spine of the anal fin is very robust and is markedly longer than the third spines. Most of the scales are ctenoid but there are no scales on the space between the eyes.
Distribution
Acanthopagrus sea breams are found in the Indian and Western Pacific Oceans from the eastern coast of Africa and the Red Sea as far east as New Caledonia, south to Australia and north to Japan.[
