 | | The Order Percopsiformes is a small order of North American freshwater fishes that includes three families: Amblyopsidae (cavefishes, four genera, six species); Aphredoderidae (pirate perches, one species); and Percopsidae (trout-perches, one genus, two species; Nelson 1994). |
 | | Trout-perch (Percopsis omiscomaycus) are aptly named, since they exhibit characters of the salmonids, such as an adipose fin, cycloid scales, and soft fin rays, as well as characters of the percids, such as dorsal and anal fin spines, and ctenoid scales (Nelson 1994). |
