Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 12 - 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 20 - 23; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 21 - 24. Head without cirri. Jaws with immovable comb-like teeth and a pair of canines posteriorly. Gill opening restricted; lower end usually opposite 3rd pectoral fin ray. Sensory pores in infraorbital and interorbital canals mostly 7 and 3 respectively. Both sexes without occipital crest.
Common in rocky shore areas. Adults feed on algae and detritus (Ref. 9137). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
