Carangoides chrysophrys

Carangoides chrysophrys differs in having no markings between bases of second dorsal-fin rays (vs. brown/black blotches); straight part of lateral line short, about 1/3 to curved part (vs. long, about equal to curved part); scaleless breast area long ventrally, extending beyond pelvic-fin origin (vs. short, not extending beyond pelvic-fin origin) and head profile just above mouth vertical (vs. gently sloped).

Carangoides coeruleopinnatus
Coastal trevally

Carangoides coeruleopinnatus

Carangoides coeruleopinnatus differs in having no markings between bases of second dorsal-fin rays (vs. brown blotches); second dorsal-fin lobe long and filamentous in young, shortening to less than head length with age (vs. lobe never filamentous but long, greater than head length).

Bumpnose trevally

Carangoides hedlandensis

Carangoides hedlandensis differs in having no markings between bases of second dorsal-fin rays (vs. brown blotches); head profile very steep (vs. gently sloped) and a bump in head profile level with the eyes, becoming more pronounced with increasing size (vs. no bump).

Carangoides malabaricus

Carangoides malabaricus differs in having no markings between bases of second dorsal-fin rays (vs. brown blotches); straight part of lateral line much shorter than curved part (vs. slightly shorter) and scaleless breast area long ventrally, often extending to second anal-fin origin (vs. short ventrally, extending to pelvic-fin origin).
