Características distintivas

Breast naked (scaleless) ventrally to origin of pelvic fins and laterally to pectoral fin base, with a small patch of scales anterior to pelvic fins., Upper jaw extends to below anterior half of eye., Adipose eyelid well developed, covering most of eye except for a vertical slit., Lateral line with a moderately long anterior arch and a straight posterior section, with 20-30 scutes on the straight part., Body depth 2.8-3.3 times in fork length (FL)., Maximum recorded length up to 100 cm FL, common to 70 cm FL. Maximum weight around 11.4 kg.

Nadadeira dorsal

Two dorsal fins; first dorsal fin with VIII spines, second dorsal fin with 1 spine and 19-22 soft rays. The anterior rays of the second dorsal fin are elongated, forming a short lobe.

Dicas de identificação

1. 1

   Breast scalation

   The most reliable distinguishing feature is the naked (scaleless) breast, extending ventrally to the pelvic fin origin and laterally to the pectoral fin base, with only a small patch of scales anterior to the pelvic fins. This contrasts with other Carangoides species that have fully scaled breasts or different patterns of scalelessness.

2. 2

   Body spots

   Presence of small, scattered dark spots on the upper flanks, particularly above the lateral line, is characteristic of adults.

3. 3

   Fin lobe length

   The relatively short anterior lobes of the second dorsal and anal fins, compared to some other large trevallies, can be a useful indicator.

4. 4

   Adipose eyelid

   Well-developed adipose eyelid covering most of the eye, leaving only a vertical slit.
