Most foxes live in forests or other wooded areas. Some species of fox prefer a habitat in a more urban environment. The specific habitat of a fox varies depending on the species.Habitat and Range . Many crinoids existed during the Paleozoic fossil era. Today, they live in the western part of the Pacific Ocean and the Atlantic Ocean.
