Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 7251)
Dark red-brown above; side pale yellow or cream, with small, dark red-brown spots; belly creamy yellow. 3 spines on vertical edge of preopercle (Ref. 26938).
A solitary species (Ref. 26340) inhabiting sandy bottom strewn with rocks (Ref. 5521). Rarely observed on reefs (Ref. 13442). Like other soapfishes, it has special skin glands that produce an irritating, mildly toxic slime (Ref. 26938).

Estimates based on models
Preferred temperature (Ref. 115969
): 24 - 28.1, mean 27.3 °C (based on 703 cells).
Phylogenetic diversity index (Ref. 82805
= 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
Trophic level (Ref. 69278
): 3.7 ±0.6 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 (22 of 100) .
