Etymology: Syncomistes: Greek, syn, symphysis = grown together + Greek, komistes, -ou = leader, driver (Ref. 45335); carcharus: The specific epithet carcharus is Latin for sharp teeth, in reference to the robust, pointed teeth of the species, relative to other Syncomistes.

Morphology | Morphometrics
soft rays: 8 - 9;
Vertebrae: 25. Syncomistes carcharus is distinguished from other congeners within the Syncomistes complex by a combination of the following characters: jaw rounded with a tapered point when viewed from below in adults (jaw shape of juveniles unknown); mouth terminal; mouth slightly oblique; teeth conical; longest dorsal ray > 16.7 % SL; longest dorsal spine > 13.4 % SL; pectoral fins > 22.8 % SL; upper caudal lobe > 29.9 % SL (Ref. 119336).
Inhabits streams, preferring deep back waters and slow-flowing portions. Forms shoals in the middle of the water column with Hephaestus jenkinsi Whitley, 1945. Occurs in clear waters over rocky substrates, usually where algae are in abundance. Found in highest abundance during snorkelling in Pitta Creek, 1km upstream from the confluence with the Prince Regent River (Ref. 119336).
