Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 20 - 22; Rückenflossenweichstrahlen (insgesamt) : 19 - 24; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 18 - 21; Wirbelzahl: 34 - 36. Body fairly elongate and strongly compressed. Mouth with fang-like teeth. The tips of both jaws with dermal processes. Gill rakers degenerated. Color is dark brown with violet tint; fin membranes black; margin of anus black (Ref. 6181).

Adults, benthopelagic to mesopelagic, dwell on the continental slope or underwater rises, migrating to midwater at night (Ref. 6181). Eggs are pelagic (Ref. 6766). Larvae and juveniles, epipelagic to mesopelagic, are rather common in oceanic ichthyoplankton and are only found in the tropics (Ref. 6181). Feed on squid, fish and crustaceans (Ref. 6181). Consumed as food (Ref. 4537).

Estimates based on models

Preferred temperature (Ref. 115969): 6.6 - 14.3, mean 9.6 (based on 988 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00363 (0.00163 - 0.00807), b=3.10 (2.91 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.71 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Preiskategorie (Ref. 80766): Unknown.
