Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 12; Rückenflossenweichstrahlen (insgesamt) : 19 - 20; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 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.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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

Preiskategorie (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);
