an order of fishes closely related to Perciformes. The body is usually laterally compressed and high. There are one to four spines in the anal fin and six to nine spines in the pelvic fins. The mouth, which protrudes when grasping food, forms a wide tube.

There are three to six families, embracing about 50 species. The fishes live in tropical and warm seas near the coasts and along the slope of the continental shelf. They are predominantly deepwater inhabitants, with some species living at depths greater than 1,000 m.

A typical representative is Zeus faber, which usually is 20–30 cm long (sometimes reaching 50 cm) and reaches a weight of 8 kg. It has a black spot on its side. The fish is distributed in the eastern part of the Atlantic Ocean and in the Mediterranean Sea; it is mainly a bottom dweller, staying at depths of 100 to 500 m. A predator, Z. faber feeds predominantly on herring, sardines, and sand eels. It has little commercial significance. The fish is the only species of the order Zeiformes that occurs in the waters of the USSR: it occasionally is found in the Black Sea.

The fishes of the order Zeiformes are marine, cosmopolitan, bathy- and benthopelagic, with preference of cold and temperate waters and found at various depths in the southeastern Pacific and Atlantic Ocean (Heemstra, 1980; Lloris, 1981, 1986; James et al, 1988; Pequeno et al., 1992; Yearsley & Last, 1998; Tyler et al., 2003; Pequeno & Matallanas, 2004; Nakabo et al., 2006; Nelson, 2006; Nolf & Tyler, 2006).
The Zeiformes are characterized by having a high and compressed body, with the dorsal and anal profile bordered by the presence or absence of small thorns or shields.
In Chile, information about of Zeiformes species is scarce, probably due to the casual captures and the limited access of the seamounts (Pequeno, 1989; Melendez et al., 2001; Pequeno et al., 1992; Pequeno & Matallanas, 2004).
For the revision and updating of the order Zeiformes of Chile, the classification criteria provided by Nelson (2006) and Eschmeyer (2015) were considered.
In Chile, the Order Zeiformes is composed of five families (Oreosomatidae, Parazenidae, Zenionidae, Grammicolepididae and Zeidae), seven genera (Cyttomimus, Grammicolepis, Neocyttus, Pseudocyttus, Stethopristes, Zenion and Zenopsis) and 11 species (C.
Tentative identification key for the Zeiformes fishes from Chile
The fishes of the Order Zeiformes fishes contains six families and 322 species.
Another relevant aspect of the Order Zeiformes in Chile is its taxonomy that differs from that presented by Pequeno (1989, 1997).
