Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 10.0 cm TL maschio/sesso non determinato; (Ref. 7251)
Spine dorsali (totale) : 11 - 13; Raggi dorsali molli (totale) : 13 - 15; Spine anali: 2; Raggi anali molli: 14 - 17. Gill opening extending ventrally to opposite 5th-11th pectoral-fin ray; segmented dorsal-fin rays 13-15; segmented pelvic-fin rays 3; last dorsal-fin spine 8.5-15.5% SL; dorsal-fin spines robust and stiff; no elongate fleshy flap present posteriorly on lower lip; infraorbital bones 5; upper lip with free dorsal margin extending around snout; fleshy lobes of lower lip almost semicircular in lateral view and separated anterioventrally by a broad shield-shaped lobe; bony interorbital width comparatively narrower; dark spot usually absent in spinous dorsal fin, but if present centered on third spine; mandibular pores 3.
Body shape (shape guide): elongated; Cross section: oval.
Herbivorous, with short chisel-like teeth used to scrape algae and detritus from surfaces (Ref. 94105). 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). Migratory behaviour is undetermined (Ref. 126106).
