Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL maschio/sesso non determinato; (Ref. 4448)
Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 8 - 9. Body is compressed (Ref. 37108). Pinkish with silvery reflections, darker dorsally (Ref. 3974). Lacks the checkerboard pattern of whitish and brown, produced by concentration of pigment at the margins of the scale pockets (Ref. 37108).
