Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 14-17; Afterflossenstacheln 0; Afterflossenweichstrahlen: 12 - 16; Wirbelzahl: 43 - 46. Last photophore of VAL series behind origin of anal and last photophore of VAV series. Aggregation of luminous tissue on head, when fully developed fish > 10 cm SL, forming transverse bar across gill cover; longitudinally oriented aggregations of luminous tubercle-like spots on body behind head and above pelvic fins. In immature fish < 6 cm SL, chin barbel fully developed, longer than head, its swollen tip forming elongate thickened rod with two flattened distal lobes (Ref. 27676).

Epi- and mesopelagic, with fishing depths to 4000 m (Ref. 58302). Found on the continental slope (Ref. 75154).

Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 12.4, mean 7.4 °C (based on 498 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00171 - 0.01014), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
