Étymologie
Kyphosus : du Grec, kyphos = une courbe, une bosse.
sectatrix : du Latin, sectatrix = adepte, membre d'un parti, d'une secte, bigot. A l'époque, il y a du surement avoir une confusion entre les espèces et les noms utilisés car pour ce poisson dans l'Encyclopédie Méthodique, Histoire naturelle - 1787 - Tome 3 - P. 356 il est mentionné : "Catesby dit qu'il s'attache au gouvernail des vaisseaux qui traversent l'Océan Atlantique. C'est de la confiance à suivre les vaisseaux dans leur course la plus rapide, que lui est venu le nom de sectatrix, qui lui a été donné par Catesby, et que Linnaeus a adopté". En Latin, saltatrix = danseuse.
Description originale : Perca saltatrix Linnaeus, 1758, transformé par Linnaeus lui-même en 1766 en Perca sectatrix Linnaeus, 1758.
Localité type : îles de Dry Tortugas, archipel des Keys, Golfe du Mexique, Floride, USA.

Description
Dorsal spines (total): 10-11; Dorsal soft rays (total): 11-12; Anal spines: 2-3; Anal soft rays: 10-12; Gill rakers on external side of lower limb on first arch: 14-18, and on upper limb: 5–8. Anal fin relatively highly elevated, with second anal-fin ray longest: 8.5-15.2 % in SL. Pectoral fin length: 13.3-24.1 % in SL. Lateral line: 63–76 scale rows in total, of which: 51-61 has pores. Longitudinal row: 60-69 scales. Precaudal and caudal vertebrae 10 and 15, respectively. Dorsal and anal pterygiophores 20-21 and 12, respectively. Body elliptical to almost circular in lateral view. Mouth terminal. Head slanting from above eye to snout, giving the profile of the head a pointed or beaked appearance. Snout as long as eye diameter. Head with relatively narrow interorbital width (8.6-13.9 % in SL). Caudal peduncle relatively long but not deep. Ctenoid scales covering body from interorbital region, cheek, postorbital region and posteriorly across the body to the caudal fin. Caudal fin not deeply emarginated. Max. length: 76.0 cm TL, common length: 50.0 cm TL. Max. published weight: 6.0 kg. Depth range: 1 - 30 m, usually: 1 - 10 m.
Color
Often grey to silvery with weak horizontal lines of slightly golden colored scales along the body, but also with a more green to bronzed coloration dorsally. Often with a white or silvery streak on the cheek underneath the eye. Occasionally, the entire body distinctively yellow (xanthic form), or with blotches or patches of black and a yellow or pale color, or more rarely, entirely white. Xanthic forms are more common at isolated oceanic islands in the Pacific Ocean. Xanthic individuals are less common in the Atlantic and Indian Ocean, but schools of yellow individuals have been recorded. Juveniles grey, but with uniformly distributed white or paler spots all over the body. The spots in juveniles can appear lighter or darker depending on both the lighting and the behaviour of the fish, with the spots being more visible when the fish are stressed.
Etymology
Kyphosus: from Greek, kyphos = bent, a hump.
sectatrix: from Latin, sectatrix = follower, bigot. First described as Perca saltatrix, but corrected to Perca sectatrix in Linnaeus 1766: p. 486, based on Catesby (1743). The name saltatrix Linnaeus (1758) was a lapsus by Linnaeus, which he himself changed to sectatrix Linnaeus (1766).
Original description: Perca saltatrix Linnaeus, 1758, Linnaeus himself changed in 1766 to Perca sectatrix Linnaeus, 1758.
Type locality: Dry Tortugas Island, Gulf of Mexico, Florida, USA.
Distribution
Circumglobal (including Caribbean Sea and western Mediterranean Sea).
Biology
Forms schools (often with other drummer species) on shallow reefs, often in the surge zone. Also occurs over algal reefs and seagrass beds, sandy and rocky bottoms, and reef flats. Juveniles, which often shelter among floating Sargassum seaweeds, can disperse across vast distances. Omnivore - feeds on benthic algae, as well as on small crabs and molluscs.
