(total): 6 - 7;
soft rays: 10. Uniformly dark brown or black with irregular markings on head and operculum and a conspicuous white semi-circular marking on shoulder at base of pectoral fin. Larger individuals mottled with irregular blotches on head and body. Pectoral, pelvic and anal fins becoming paler distally.
Occurs in rock pools and deeper reefs, usually in narrow crevices where fine silt accumulates. Secretive and usually only the head is seen protruding out of the crevice; will retreat when disturbed.

Estimates based on models
Preferred temperature (Ref. 115969
): 13.2 - 18.9, mean 16.4 °C (based on 107 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
