Etymology: Ancistomus: Greek, agkale, agkalos = hook, something curved + Greek, stoma = mouth.

In Ambruster et al., 2015 (Ref. 99824), no characteristics were found to separate Ancistomus spinosissimus from A. micrommatos and A. spiloma, and these may represent the same species.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
