Duri punggung (Keseluruhan (total)) : 11; duri punggung lunak (Keseluruhan (total)) : 20; Duri dubur: 3; Sirip dubur lunak: 17. This species is distinguished from its congeners by the following characters: less number of pored scales in the lateral line (27 vs. 37-46); longer snout (35.9% in HL vs. 28.2-35.5%); shorter first dorsal ray (12% in SL vs. 16.6-26.6%); longer caudal peduncle (8.5% in SL vs. 4.2-8.2%); shorter caudal fin (15.9% in SL vs. 19.8-25.9%); with a dark brown pelvic-fin spine (vs. white) (Ref. 116443).

Areas of collection vary from sheltered rocky outcroppings which are heavily covered by fine sediment to areas exposed to strong currents. Ambient seawater temperature varied between 19 and 21°C during dives conducted in April-May over several years. Azooxanthellate gorgonians, black corals, and solitary stony corals were the most abundant benthic invertebrates in this area (Ref. 116443).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02239 (0.01097 - 0.04568), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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