Morfologie | Morfometrie
Dorsale stekels (totaal): 11 - 13; Dorsale zachte stralen (totaal): 13-15; Anale stekels 2; Anale zachte stralen: 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.
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).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00335 - 0.01640), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.8 ±0.2 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
