Etymology: Ancistrus: Greek, agkistron = hook (Ref. 45335);  maximus: From the latin adjective maximus, meaning the largest, in reference to the off-the-chart size of this species (Ref. 103398).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 8; Anal soft rays: 5. Diagnosis: Ancistrus maximus is distinguished from all congeners, except A. dolichopterus, A. fulvus and A. latifrons, by having more branched rays in the dorsal fin (8 vs. 7); Ancistrus maximus is distinguished from A. dolichopterus by its color pattern, overall body color dark brown with reddish-orange spots almost half the size of pupil in adults and with reddish-orange bands on distal portion of dorsal and caudal fins only in juveniles vs. overall body color black or dark-gray with numerous white dots and with white band on distal portion of dorsal and caudal fins throughout life; Ancistrus maximus differs from A. latifrons by the absence of hypertrophied ('spiny') odontodes in lateral plates (vs. presence of elongate and strong 'spiny' odontodes later­ally oriented in A. latifrons); Ancistrus maximus differs from A. fulvus by dorsal-spine length 27.9-34.5 % SL (vs. 25.7); pectoral-spine length 30.7-42.6 % SL (vs. 26.6) and by total lateral median plates 24-25 (vs. 22) (Ref. 103398).

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=0.01318 (0.00580 - 0.02997), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
