Percopsiformes is a small order of ray-finned fish, comprising the trout-perch and its allies. It contains just nine species, grouped into three families.[2]

They are generally small fish, ranging from 5 centimetres (2.0 in) to 20 centimetres (7.9 in) in adult body length. They inhabit freshwater habitats in North America. They are grouped together because of technical characteristics of their internal anatomy, and the different species may appear quite different externally.[1]

Families

* Percopsidae (trout-perches)
* Aphredoderidae (pirate perch)
* Amblyopsidae (cavefishes)
