Etymology: Otocinclus: Greek, ous, oto = ear + Latin, cinclus = latticework; in allusion to the holes of the head in the ears (Ref. 45335); cocama: Named for the Cocama-Cocamilla Indians that used to be dominant in the lower Ucayali and Marañon rivers..

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 2; Μαλακές ραχιαίες ακτίνες (συνολικά) : 7; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 5; Σπόνδυλοι: 28. Can be distinguished from all its congeners by the following putative autapomorphies: unique, distinct color pattern consisting of vertically elongated blotches spanning from the dorsal midline to the ventral border of flanks; complete lateral line, without the gap plates (midbody plates without lateral line perforations) present in other Otocinclus. Can also be differentiated by having high number of teeth (30-45 in premaxilla and 23-36 in dentary). Differs from Otocinclus huaorani, Otocinclus mura and Otocinclus bororo by having a small metapterygoid channel and one W-shaped mark in the caudal fin (Ref. 57860).
Facultative air-breathing in the genus (Ref. 126274); Found in a medium size creek with clear water and lost of marginal vegetation (Ref. 57860).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
