Distribution
Temperate Australasia
Description
Possessing fewer scales along the lateral line (67–79 cf. 96–115), a rear margin of the upper jaw that slopes 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.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (4.2% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Many (19 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
