Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 52 - 55; Duri dubur: 0; Sirip dubur lunak: 34 - 40. Pectorals rounded, pedunculate (Ref. 6885). Generally of a chocolate color (Ref. 6885). Young more robust, with an expanded and rounded caudal fin, 5 pelvic rays, and a brown and yellow irregularly blotched with faint purple color, dusky on fins (Ref. 6885).

Adults occur near bottom; juveniles in shallow water or offshore near the surface (Ref. 50277). Feeds on jellyfish (Ref. 50277), fishes and squids (Ref. 2850), as well as octopuses (Ref. 4525).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 14.1, mean 6.2 °C (based on 1370 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.57 se; based on food items.

Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (K=0.13; Fec=293,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100).
