Antigonia is a genus of small to medium-sized marine fish that occur worldwide in all warm and temperate oceans, mostly at depths of 50 to 600 meters ( bentho pelagic ).
features
Antigonia species grow to be 5.5 to 30 centimeters long. Their body is diamond-shaped, very high back, strongly flattened on the sides and covered with small comb scales, which are usually covered with large raised ridges. Your dorsal fin is supported by eight or nine spines and 26 to 38 soft rays, the anal fin by three spines and further (approx. 25–35) soft rays. The caudal fin has ten branched fin rays , so that there are a total of twelve main rays and seven or eight secondary rays . All Antigonia species are reddish and silvery in color. The nasal ( nasal bone ) articulates with the extension of your palatine ( gum bone ) that is aligned with the maxillary , which improves the olfactory function. The mouth can be extended far (protraktil - feeding of smaller, volatile animals such as shrimps, fish).
Systematics
The genus Antigonia was introduced in 1843 by the English naturalist Richard Thomas Lowe together with the boarfish family (Caproidae), to which Antigonia was assigned. The genus is not particularly closely related to the only other species in the Caproidae family, the boarfish , and the assignment was only provisional. The Australian ichthyologists Anthony Gill and Jeffrey M. Leis introduced the family Antigoniidae in October 2019 with Antigonia as the only genus. At the same time they put the Antigoniidae in the order of the surgeon fish-like (Acanthuriformes). Antigonia shares a unique trait (a synapomorphism ) with the rest of the surgeonfish , which was used to diagnose order. In the larvae and adult specimens of Antigonia and the other surgeonfish species, the regrowing teeth grow on the outside of the jaw and replace their predecessors in groups.
Antigonia - fossils are from the Eocene and Miocene known. One site is the Monte Bolca near the Italian city of Verona .
