Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 11 - 12; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8. Silvery with faint, red crossbars; dead specimens almost white or purple.
Found over rocky substrates of coastal waters. Juveniles stay in sheltered areas of estuaries (Ref. 5213). Large specimens caught from the shore only when seas are rough (Ref. 3198). Marketed fresh, whole or dried.
Also reported as a 'rudimentary hermaphrodite' or 'late gonochorist' where individuals posses an immature intersexual gonad but mature as either male or female fish with no eveidence of sexual reversal (Ref. 28504).
