Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 5 - 12; Rückenflossenweichstrahlen (insgesamt): 2; Afterflossenstacheln 14-17; Afterflossenweichstrahlen: 125 - 145; Wirbelzahl: 225 - 239. Presence of palatine and dentary teeth in two or more rows. Numerous dorsal spines. Small specimens are pale tan or pale bluish gray, large specimens are dark brown (Ref. 37108).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Benthopelagic (Ref. 58302) and epibenthic (Ref. 58426). Not uncommon in depths around 180 m off Iceland and Greenland. Individuals with nearly ripe eggs have been found in late autumn off Iceland. Mostly found at depths well below 200 m, but enters slightly shallower water on Grand Banks in Canada (Ref. 7251). Feeds primarily on sea anemones (Ref. 4449).

Estimates based on models

Preferred temperature (Ref. 115969): 1 - 14.9, mean 6.1 °C (based on 2531 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5161   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00191 (0.00103 - 0.00354), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Generation time: 27.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming tmax>10).
Verwundbarkeit (Ref. 59153):  High to very high vulnerability (69 of 100) .
Nutrients (Ref. 124155):  Calcium = 13.6 [6.6, 24.7] mg/100g ; Iron = 0.204 [0.112, 0.377] mg/100g ; Protein = 17.1 [16.0, 18.3] % ; Omega3 = 0.215 [0.106, 0.424] g/100g ; Selenium = 24.5 [10.1, 58.2] μg/100g ; VitaminA = 12.3 [2.7, 49.0] μg/100g ; Zinc = 0.419 [0.265, 0.667] mg/100g (wet weight);
