Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 10; Spine anali: 3; Raggi anali molli: 6. This species is distinguished from its congeners by the following cahracters: brown-colored lateral line; mean interorbital width 4.1% of SL (vs. 5.2-6.9%); mean snout length 8.9% of SL (vs. 9.8-11.1%); mean orbit diameter 4.5% of SL (vs. 5.4-7.3%); mean mandible length 15.7% of SL (vs. 19.9-21.6%); differs from C. undecimalis by the number of circumpedancular scales 18-22, usually 19-21 (vs. 22-28, usually 24-27) (Ref. 121036).
Cross section: compressed.
This species was observed in the more saline waters, close to the outlet channel of the lagoon to the sea, as confirmed by local fishermen. It was also found in the center of the lagoon. None of the specimens collected from the lagoon were preserved, and these were lost, but a picture of the largest individual (53.55 cm SL) was taken (Ref. 121036).
