Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 10 - 13; Vertebrae: 36. Diagnosis: Notoglanidium akiri differs from other species in the genus in having: an average interorbital distance, 24.1-32.8% of head length vs. smaller in N. boutchangai, N. depierrei, N. pallidum and N. pembetadi, and larger in N. maculatum and N. thomasi; a large eye diameter, 6.6-10.5% of head length vs. smaller in N. maculatum and N. pallidum; a deep adipose fin, 4.7-7.3% of standard length vs. less deep in other species except N. macrostoma and N. walkeri; an average combined premaxillary tooth plate width, 22.0-26.1% of head length vs. broader in N. boutchangai and N. macrostoma and smaller in allother species except N. depierrei and N. pembetadi; only seven soft branched dorsal-fin rays, vs. more than 8 in N. depierrei, N. maculatum, N. pallidum, N. pembetadi, N. thomasi and N. walkeri; and a high dorsal-fin spine length, 9.8-12.8% of standard length vs. shorter in all other species except 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=0.00955 (0.00503 - 0.01813), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
