Related to the coelacanths were the Rhipidistia, the only fishes to have true internal nostrils, and an internal fin skeleton very similar to that of the limb of a tetrapod.

Except for the Kentucky cave fishes and trout perches, which are confined to the fresh waters of North America, they are mainly stout-bodied, marine fishes. Most are carnivores and many species are viviparous. Some occur in shallow waters, for example the toadfish and

The 8000 or so described species fall into 12 orders, one of which, the Perciformes, contains three-quarters of them, arranged in over 20 suborders. Here, one finds many
