Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 14 - 16; Anal spines: 3; Anal soft rays: 7; Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: D 14-16, modally 15 segmented dorsal rays with fourth dorsal spine longest; pectoral fin with 13-14 unbranched rays; lateral line complete, 27-30 tubed scales; lower part of preopercle with two enlarged antrorse spines; predorsal scales extending anteriorly to anterior part of interorbital area (Ref. 123579).
Cross section: compressed.
Known only from beam trawls and sled captures. From video camera footage, habitat consist of low relief silty sand/mud with dense patches of crinoids and erect, cup-shaped sponges (Ref. 123579).
