Antigonia is a genus of marine ray-finned fish belonging to the family Caproidae, the boarfishes. This genus is found in the warmer oceans around the world and is the only extant genus in the subfamily Antigoniinae.

Taxonomy

Antigonia was first proposed as a monospecific genus in 1843 by the English zoologist Richard Thomas Lowe when he described Antigonia capros as a new species. [1] When Lowe described A. capros he gave its type locality as Madeira. [2] The 5th edition of Fishes of the World classifies this genus in the Antigoniinae, a subfamily of the Caproidae, within the order Caproiformes, [3] as do other authorities. [4] However, other authorities classify this taxon as a family, the Antigoniidae, and classify and the Caproidae in the order Acanthuriformes. [5]

Etymology

Antigonia, the genus name, was not explained by Lowe but it is probably a combination of anti, meaning "against", and goneos, which means "ancestor". This may be reference to how A. capros is so distinctive yet seems to elucidate the ancestry of relayed forms which Lowe felt were randomly classified before he described A. capros. [6]

Species

Antigonia contains the following recognised species: [7]

Characteristics

Antigonia boarfishes have highly compressed, rhomboid shaped bodies with convex dorsal and ventral profiles. The small head bears bony ridges that radiate, has a concave dorsal profile and a clear crest along the nape. The eyes are large and the mouth is small, upward pointing, opens at the front and has protrusible jaws. The continuous dorsal fin has 8 or 9 spines, the third spine being the longest. The anal fin has 2 or 3 spines with the first spine being the longest. The anal spines are separated from the anal fin rays. The long bases of the soft rayed dorsal and anal fins have scaly sheaths. The roundly pointed pectoral fins have a single spine and 12 or 13 fin rays. [8] The largest species is the deepbody boarfish (A. capros) with a maximum published total length of 30.5 cm (12.0 in) while the smallest is A. kenyae at 4.4 cm (1.7 in). [7]

Distribution

Antigonia boarfishes are found in the tropical and temperate Indian, Pacific and Atlantic Oceans. [7]
