Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 72 - 89; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 55 - 71; Wirbelzahl: 59 - 64. Diagnosis: head oval-shaped in dorsal outline; snout slightly rounded; eyes dorsally located (Ref. 248). Frontal fontanella short and wide/squat (Ref. 248, 57129). Occipital fontanelle rather long and oval-shaped; "dermosphenotic" and supraorbital bones joined; tooth plates small; suprabranchial organ not well developed (Ref. 248). Distance between occipital process and dorsal-fin base short (4.9-9.3% of standard length); pectoral spine serrated on both sides (Ref. 57129). Coloration: live fish as well as preserved specimens very light-coloured: back and sides yellowish brown, belly lighter; some specimens show submarginal blackish marks on vertical fins (Ref. 57129).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00416 - 0.01447), b=2.95 (2.79 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.47 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
