Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 12 - 13; Afterflossenweichstrahlen: 16. Three equidimensional spiny rays present on the posttemporal spine. In front of the dorsal fin is a long, pigmented protuberance, reaching to the median line of the body. Photophores in the anal series few, 8-9. A wide gap equal to the length of the group of subcaudal photophores present between the anal and subcaudal photophores. Spiny scales absent on preanal, anal and subcaudal photophores. Trunk relatively deep body; caudal peduncle narrow (Ref. 26037).

Estimates based on models

Preferred temperature (Ref. 123201): 11.6 - 15.2, mean 12.7 °C (based on 15 cells).

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

Bayesian length-weight: a=0.02291 (0.01031 - 0.05092), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives

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).
