पृष्ठीय रीढ़ (सम्पूर्ण) : 12; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 19 - 20; गुदा कांटा: 3; ऐनल सौफट रेज़: 14 - 16.

Usually solitary. Found in rocky, boulder strewn areas (Ref. 5227). Close relatives are known to pinch off and eat tube feet of sea urchins and other echinoderms. Also feed on crustaceans, worms and other small invertebrates (Ref. 4930). Because they live in relatively deeper waters, they are seldom collected, thus, rarely seen in the aquarium trade (Ref. 4930). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 14.2 - 22.9, mean 16.9 °C (based on 40 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02239 (0.01117 - 0.04486), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.34 se; based on food items.

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 64.6 [28.6, 132.6] mg/100g; Iron = 0.852 [0.454, 1.592] mg/100g; Protein = 19.3 [18.0, 20.5] %; Omega3 = 0.213 [0.111, 0.406] g/100g; Selenium = 21 [9, 45] μg/100g; VitaminA = 29.5 [6.8, 126.0] μg/100g; Zinc = 0.963 [0.587, 1.498] mg/100g (wet weight);
