Perch have "rough" scales. On the front end of the fish, there are two dorsal fins. The first one is spiny and the second is soft. There is also an anal fin, which is also spiny, and a caudal fin.
There are three living species in this genus:
Perch are carnivores, They choose waters where smaller fish, shellfish, and insect larvae are plentiful.
They are found in parts of the United States in freshwater ponds, lakes, streams, or rivers. These fish can be found in fresh water all over the world. They live in the Great Lakes region, in particular Lake Erie.
The fish like bodies of water with vegetation and debris. In the spring when the perch spawns, they use vegetation to hide their eggs from predators.
