  Amblyopsidae
One of the facts that has been very controversial about the phylogeny of this order is that they show primitive conditions such as the presence of an adipose fin, which suggests character reversal in their evolutionary history.
The Amblyopsidae is a freshwater family distributed in the southern and eastern (unglaciated) United States (Figure 1).
They are characterized by having a large, flattened head, oblique mouth, strongly protruding lower jaw, large branchial cavity (probably for oral incubation), a jugular vent (anus), and small embedded cycloid scales, except in the head which is naked.

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).
