Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 9. Longitudinal scales 33-34; transverse scales 11-12; predorsal scales 2-6. Maxillary extends beyond midline of eye, upper jaw prominent; lips fleshy. Gill opening small, only from upper to lower margin of pectoral fin base. Head naked above behind eye. Scales on predorsal and behind pectoral cycloid; on other part of body ctenoid. Spines of 1st dorsal about equal (Ref. 43550).

Biology     Glossary (e.g. epibenthic)

Adults occur in rocky creeks (Ref. 2847). Also found in small, steep-gradient creeks, usually within 20 km of the sea (Ref. 2847).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [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).
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
