Vertebrates are animals with a backbone or spine, a defining characteristic that sets them apart from invertebrates. This internal skeleton, made of bone or cartilage, supports the body, protects the spinal cord, and provides muscle attachment points. Vertebrates, including fish, amphibians, reptiles, birds, and mammals, have adapted to a variety of habitats and environmental conditions.
Arizona's diverse habitats, from arid deserts and rugged mountains to lush riparian zones and temperate forests, support a wide array of vertebrate species. These animals, from the towering American Bison to the elusive Desert Tortoise, play vital roles in their ecosystems, contributing to the state's rich wildlife and natural environment. Understanding and exploring these vertebrates enhances our appreciation of Arizona's natural beauty and biological diversity.
