Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 17; Μαλακές ραχιαίες ακτίνες (συνολικά) : 18 - 20; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 6 - 7; Σπόνδυλοι: 35. Adults have a short-based anal fin, pectoral fins with thickened lower rays, and are grey to blue-black with lighter mottling on the sides and light spots on the fins (Ref. 33616). It is distinguished from its congeners in having larger body scales (lateral-line scales 72± 82 vs. 83± 120) and absence of vomerine teeth (Ref. 86913).
Found on shallow exposed rocky shores, aggregating in high-energy zone, just below foaming surface to depths of about 10 m (Ref. 9002); in kelp and weed areas (Ref. 86913). Feed on either loose or attached weeds and algae (Ref. 9002); mainly consisting of Corallina pilulifera,
together with smaller quantities of Ulva actuca, Jania and filamentous species such
as Sphacelaria sp. (Ref. 86913).
