Look for the very deep, compressed, and almost circular body profile.
Coloration and Spots
The silvery body with distinct, irregular rows of dark spots on the upper flanks and dorsal fin is a key identifier.
Pectoral Fins
The long, sickle-shaped pectoral fins are very characteristic and often extend past the anal fin origin.
Mouth
Note the small, protractile mouth.
