Body Shape
Look for a very deep, compressed, and oval-shaped body, which is characteristic of pompanos.
Mouth
Observe the small, subterminal mouth, which is positioned slightly below the tip of the snout.
Lateral Line
Crucially, check for the absence of scutes (bony plates) along the lateral line, a key feature distinguishing it from many other jack species.
Fin Coloration
Note the yellowish coloration of the fins, particularly the caudal and anal fins, which can be quite vibrant in younger individuals.
Snout
The snout is relatively short and blunt compared to some other Trachinotus species.

Trachinotus carolinus
T. blochii generally has a deeper body and a blunter snout than T. carolinus. The fin coloration can also differ, with T. blochii often having more pronounced yellow fins. T. carolinus is found in the Western Atlantic, while T. blochii is Indo-Pacific.
Permit
Trachinotus falcatus
While sometimes used as an alternative name for T. blochii, the true Permit (T. falcatus) is a distinct species found in the Western Atlantic. T. falcatus typically grows larger, has a more elongated dorsal and anal fin lobe, and often exhibits a more silvery-white body with less yellow in the fins.
African Pompano
Alectis ciliaris
The African Pompano has extremely long, filamentous rays in its dorsal and anal fins, especially as juveniles, which are absent in T. blochii. It also has a more angular head profile.
