Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 24-25; Afterflossenweichstrahlen: 40 - 41. Two pectoral rays (one as tiny rudiment), and a barbel with three branches arising proximal to midlength of the stem, followed by two ovoid swellings (bulbs), either contiguous or separated, and a large terminal bulb. The tear-shaped terminal bulb larger in diameter than the stem or proximal bulbs, with the acuminate end posteriad and upturned dorsally, and bears multiple filaments and bulblets in two groups, one at its anterodorsal surface and one at its terminus. Barbels relatively short (<= 20% standard length) (Ref. 51076).

Probably undergoes some form of vertical migration from below 500 m during the day and within the upper 100 m at night (Ref. 51076).

Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 8.8, mean 3.6 °C (based on 14 cells).

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

Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.8 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tmax>3).

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