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).
