Summary:

A deep, very compressed silvery-blue to silvery-grey trevally, silvery-white below, with a black blotch on the front part of the dorsal fin. Juveniles are almost diamond-shaped with 5 chevron-shaped dark bands on the sides. 

Juveniles, with their extremely long filaments trailing from the dorsal and anal fins, appear to mimic box jellyfishes with long trailing tentacles.
