Identification	Pterygoplichthys can be identified by the number of rays in the dorsal fin. Ten or more dorsal rays (usually more than 10) indicates that it's a Pterygoplichthys. Most other plecos have 8 or fewer rays (in particular the larger Hypostomus species that are most likely to be confused with Pterygoplichthys). Diagnosis (translated from French): Pterygoplichthys parnaibae is distinguished by a dark coat with clear spots and vermiculations on the whole body and fins, associated with the presence of a high preoperculum and garnished with numerous hooks, particularly developed on the upper part of its posterior margin. P. parnaibae bears a similar appearance with P. joselimaianus and P. lituratus. The three are collected from different waterways, with P. parnaibae originating in the Rio Parnaiba basin in the state of Maranhao, P. joselimaianus originating in the Rio Tocantins basin in the state of Goias, and P. lituratus originating in the Rio Madiera basin, States of Rondonia and Mato Grosso.
Sexing	Comparison of the genital papilla in mature fish shows the differences in the sexes to the trained eye. In males this is a small yet thick stump which noticeably protrudes from the fish's undercarriage. In females it is less obvious and is recessed or lies flat with the body.
