Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 21-22; Anal spines: 3; Anal soft rays: 20 - 21. Colour grey-brown with indistinct dark bars on side of body, the 5 to 7 peduncular plates black. Body depth of subadults about 2 times in SL, the body becoming more elongate with age (to as much 3 times in SL in large adults). Adults developing a pronounced protuberance anteriorly on snout (Ref 9808).

Biology     Glossary (e.g. epibenthic)

Occurs along rocky shores and feeds on benthic algae. Juveniles found in estuaries and bays (Ref. 9710).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 18.1 - 25.4, mean 23.3 (based on 108 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.30 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
