Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 150 cm TL male/unsexed; (Ref. 1602); common length : 50.0 cm TL male/unsexed; (Ref. 30573)
A secretive inhabitant of sandy and rocky bottoms, crevices and ledges of seaward reefs. It feeds primarily on xanthid crabs, but also on other crustaceans, mollusks and sea urchins (Ref. 9710, 48635). Benthic from 1-39 m, usually at <4 m (Ref. 58302). Possibly a protogynous hermaphrodite (Ref. 32169). Minimum depth reported taken from Ref. 30874.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29.1, mean 28 °C (based on 1176 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00051 (0.00025 - 0.00106), b=3.25 (3.09 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.43 se; based on food items.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Very high vulnerability (81 of 100) .
