Short description Identification keys | Morphology | Morphometrics
This species is distinguished from its congeners in having very prominent tubes externally
visible along all of the lateral line, and dense single and double prickles, readily apparent to the unaided eye, covering the body; head is fairly slender and head tubercles are well developed, as are the infraorbital(non-paired) and preopercular spines; peduncle short and relatively deep (Ref. 58914).
Caught by bottom trawl (Ref. 58914).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
