Pseudocaranx wrighti

Possessing fewer scales along the lateral line (67–79 cf. 96–115), a rear margin of the upper jaw that slopes forwards rather than is vertical, small size, and a rounded jet-black spot on the opercle edge that is about the same size as the pupil of the eye, rather than a more elongate and diffuse black spot. Unlike its close relatives, it also never develops yellow colouration along the midline or on fins. Pseudocaranx wrighti has long been confused with the silver trevally Pseudocaranx georgianus and with Pseudocaranx dentex, a closely related trevally found in the Atlantic. P wrighti is the smallest of the genus, with maximum total length unlikely to exceed 30cm.

The species can occur in mixed schools with P georgianus. Both species look extremely similar when the yellow mid line colour is faint in P georgianus individuals. The rear margin of the upper jaw is only visible in detailed photos. An imaginary line drawn continuing the angle of the rear margin will emerge well forward of the eye for P wrighti. With P georgianus, that line will be emerge close to, or even through the eye, depending on how you are viewing the individual.

In a potentially mixed school of P georgianus and P wrighti, individuals of 35cm or greater are considered to be P georgianus. Smaller individuals could be either species.
