Short description Morphology | Morphometrics

Dorsal soft rays (total): 11; Anal soft rays: 29 - 31; Vertebrae: 39 - 41. Can be distinguished by having dark blotch at the humeral region, a character shared only with Acestrocephalus boehlkei and Acestrocephalus stigmatus. Differs from Acestrocephalus stigmatus by having 25-27 anal-fin rays (vs. 29-31), and 7-8 gill-rakers (vs. 5-6). This species has a quite peculiar general structure of the pseudotympanum which differs from that of Acestrocephalus stigmatus and all the other species of Acestrocephalus examined. Acestrocephalus maculosus has very reduced muscular hiatus as a result of the great development of the obliquus superioris muscle covering the anterior portion of the swim bladder. This makes the opening anterior to first pleural rib, this and the second pleural rib as well as the obliquus inferioris muscle not visible (Ref. 75890).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00415 - 0.02411), b=3.08 (2.87 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±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).
