Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 12-16; Afterflossenstacheln 0; Afterflossenweichstrahlen: 9 - 12; Wirbelzahl: 34. Diagnosis: Notoglanidium thomasi differs from all congeners in the large interorbital distance, 41.0-46.7% of head length vs. less than 37% in all other species (Ref. 94168). It differs from other species in the genus in having: a rather large eye diameter, 9.1-12.5% of head length vs. smaller in N. depierrei, N. maculatum and N. pallidum; a small combined premaxillary tooth plate width, 11.9-18.2% of head length vs. larger in N. akiri, N. boutchangai, N. macrostoma and N. pembetadi; and a relatively large number of soft dorsal-fin rays, 12-16 vs. less in N. akiri, N. boutchangai, N. depierrei and N. macrostoma (Ref. 94168).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00221 - 0.01248), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 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).

Preiskategorie (Ref. 80766): Unknown.
