Perches are two species of fish that belong to the family Percidae. They belong to the kingdom of Animalia, under the phylum of Chordata and subphylum Osteichthyes. Confusingly, the name perch may apply to a wide variety of fish. The order to which perches belong to, Perciformes, has its roots in both Greek and Latin. Perke means "spotted" in Greek, while forma in Latin means "shaped."
There are two kinds of perches. One of which, the European perch, is native to Eurasia, while the other, the yellow perch, is native to North America.
