Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 19; Anal soft rays: 9. This species is distinct with a combination of the following characters: minute esca, as a simple filament (possibly damaged); illicium with thick base, thin distally, no dermal spinules, length about 18% SL, 2.7 times in head length; close-set, embedded, nonimbricate, spiny scales cover the entire body; scale bases variable in shape, dendritic to narrowly thallate, with long unicuspid or bifurcate spinules (except for those closely associated with pores of the acoustico-lateralis system); adpressed spinules, posteriorly directed, originating from posterior region of scale base, apical spines moderately divergent; second dorsal-fin rays 17, fin base 64% SL; length of second dorsal-fin spine 1.3 times length of longest ray of second dorsal fin; anal-fin rays 9; pectoral-fin rays 9; fresh coloration unknown, pale in preservative with darker markings on first dorsal fin and membranes of pectoral, pelvic and caudal fins (Ref. 82446).

A benthic species (Ref. 75154) which occurs inshore (Ref. 7300, 75154).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6251 [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): 3.4 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
