The classes Myxini and Hyperoartia only have one creature per class, the former being hagfish and the latter being lampreys. The class Myxiniare found anywhere from the depths of the sea to the shallowest areas of the oceans. The Hyperaortia originated in the Atlantic Ocean and have migrated to the Great Lakes. The next class, Placodermi, are an extinct group of armored fish. The class Chrondrichthyes are cartilaginous fish found alongside the class, Actinopterygii, otherwise known as the bony fish, in various aquatic environments. The next several classes are more well known in basic science classes. Class Amphibia are amphibians known as the first creature to have limbs and now are commonly live near water. Class Reptilia evolved from the class Amphibia during the Carboniferous period and now primarily reside in warm dry climates. Classes Aves and Mammilia both evolved from the class Reptilia during the Jurassic period and now reside in a diverse environments ranging from mountains to
