Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 3132)
A set of 4 long spines with their bases near dorsal- and anal-fin bases and their pointed ends extending over caudal peduncle. Two very long spines (longer than rays of pectoral fins) in pectoral-fin axil (Ref 9680).
Found on soft bottoms to at least 30 m (Ref. 9680). Presumably feeds on hard-shelled invertebrates (Ref. 9680). Frequently trawled but not marketed (Ref. 9680).

Estimates based on models
Preferred temperature (Ref. 123201
): 23.2 - 28.2, mean 26.9 °C (based on 295 cells).
Phylogenetic diversity index (Ref. 82804
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.04677 (0.01931 - 0.11328), b=2.82 (2.61 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (20 of 100).
