Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 18; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 23. Diagnosis: The body of Heteromormyrus pauciradiatus is shorter and deeper and the head is deeper than in other Heteromormyrus species; body depth 25-31% of standard length, head depth 84-97% of head length; predorsal distance is 66-70% of standard length, more than in other Heteromormyrus species; the caudal peduncle is deeper than in other Heteromormyrus species, caudal peduncle depth 46-55% of caudal peduncle length; the eye is small, 12-15% of head length (Ref. 128501).

Estimates based on models

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

Bayesian length-weight: a=0.00562 (0.00244 - 0.01296), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±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).
