Taxonomic Remarks
Regarded as nomina dubia by Sakai & Nakabo, 2014 (Ref. 95333). See explanation of the correct name choice to Kyphosus sectatrix (Linnaeus, 1758) versus saltatrix in Eschmeyer (CofF ver. Oct. 2012: Ref. 92135).
Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin récifal; profondeur 1 - 30 m (Ref. 9626), usually 1 - 10 m (Ref. 40849). Subtropical; 46°N - 29°S, 98°W - 16°E

Maturité: Lm ?  range ? - ? cm
Max length : 76.0 cm TL mâle / non sexé; (Ref. 5288); common length : 50.0 cm TL mâle / non sexé; (Ref. 3397); poids max. publié: 6.0 kg (Ref. 40637)
Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 11 - 12; Épines anales: 3; Rayons mous anaux: 11. Gray overall, with faint yellow lines on side and yellow line from corner of mouth to preopercle (Ref. 26938). Upper part pf opercular membrane blackish. The young may display pale spots nearly as large as eye on the head, body and fins (Ref. 13442). Each jaw with a regular row of close-set, strong, incisor-like, round-tipped teeth of a peculiar hockey stick-shape, their bases set horizontally, resembling a radially striated bony plate inside mouth (Ref 52729).
Body shape (shape guide): fusiform / normal.
Inhabits shallow waters, over turtle grass, sand or rocky bottom and around coral reefs (Ref. 3725); in mangroves (Ref. 138854). Young commonly found among floating Sargassum seaweeds (Ref. 3725). Feeds on plants, mainly on benthic algae, as well as on small crabs and mollusks (Ref. 6547, 44187). Also feeds on spinner dolphins’ feces and vomits at Fernando de Noronha Archipelago, southeast Atlantic. The offal feeding may be regarded as a simple behavioral shift from plankton feeding to drifting offal picking (Ref. 48727). Marketed fresh (Ref. 3725).
