Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 11; Afterflossenweichstrahlen: 33 - 39; Wirbelzahl: 37 - 39. Among the species of Acestrocephalus with dark humeral blotch absent, this species can be separated from Acestrocephalus sardina and Acestrocephalus nigrifasciatus by possessing a smaller eye (28.0- 31.7 vs. 32.6-36.5 in Acestrocephalus nigrifasciatus and 31.3-37.4 in Acestrocephalus sardina); and an oblong dark blotch at caudal base instead of the triangular dark blotch present on the caudal base of those two species. Distinguished from Acestrocephalus pallidus by having an oblong dark blotch at caudal base (vs. absence of dark blotch); and differs further from Acestrocephalus pallidus by the shape of the muscular hiatus of the pseudotympanum and the muscular arrangement around it. Can be diagnosed from Acestrocephalus anomalus by having more teeth in the posterior row on dentary (28-36 vs. 23-28) and fewer teeth in the external tooth row on premaxilla (6-8 vs. 8-11) (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): 3.7 ±0.6 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).
