🐟 Physical Description

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) . : elongated; Cross section: flattened.
