Vertebrates are a diverse group of animals characterized by having a backbone or spinal column. This group includes familiar animals such as mammals, birds, reptiles, amphibians, and fish. Vertebrates are known for their complex structures and systems, which allow them to adapt to various environments around the world. These animals play crucial roles in ecosystems and exhibit a wide range of behaviors and adaptations. For instance, birds are known for their ability to fly, while fish have adapted to life in water. The study of vertebrates helps scientists understand evolution, biodiversity, and the health of our planet.
