Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 13 - 14; Anale stekels: 3; Anale zachte stralen: 12 - 14. Large, black, saddle-shaped blotch on upper caudal peduncle (Ref. 26938). Silvery, about nine faint narrow dark bars may be visible on upper two-thirds of body (Ref. 13442).
Occur in clean turbulent waters along open rocky coasts, usually in surf areas (Ref. 7251). Juveniles are frequently found in littoral pools between rocks (Ref. 9626). Individuals up to 10 cm are caught in shallow waters, often in sandy shores or in seagrass (Thalassia) beds (Ref. 9626). Maximum weight of 2500 g based on confirmed reports from Uruguay (L.A. Pereira, pers. comm., 6/12/01).
