Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following set of characters: D VI + I, 8, the second and third spines elongated, reaching to base of fifth or sixth segmented ray of second dorsal fin when adpressed; A I,8; pectoral rays 16; the fifth pelvic ray branched, 56-64% length of fourth pelvic ray; the bony interorbital about equal to pupil diameter; the predorsal, cheek, and opercle are fully scaled; pattern of cephalic sensory papillae includes 5 transverse rows below eye; colour in life brownish with pink zone along upper side and 7 darker brown saddles on back interspersed with smaller golden saddles, a narrow white bar behind eye, and a yellowish bar at the base of pectoral fin (Ref. 100512).
Numerous individuals were found along the vertical, stern section of the outer hull of the vessel in about 23-28 m depth. The iron hull was completely encrusted with marine growth, especially algae, gorgonians, tunicates, and sponges. The fishes either rested on the bottom or hovered in midwater usually in small groups (Ref. 100512).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
