Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 11; Rayons mous anaux: 36 - 40; Vertèbres: 38 - 39. Can be distinguished from Acestrocephalus boehlkei, Acestrocephalus maculosus and Acestrocephalus stigmatus by the absence of dark humeral blotch characteristic of these species. Differs from Acestrocephalus sardina and Acestrocephalus nigrifasciatus by having smaller eye and fewer maxillary teeth (30-38 vs. 40-46). Can be separated from Acestrocephalus acutus by possessing only scattered dark chromatophores instead of the typical oblong dark blotch on the caudal-fin base of that species and the first pleural rib, the cavity anterior to it and the obliquus inferioris muscle visible (vs. entirely covered by the fibers of the obliquus superioris muscle in Acestrocephalus acutus (Ref. 75890).

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).
Niveau trophique (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
