What do we call an animal that possesses a backbone?

An animal that possesses a backbone is classified as a vertebrate. This group includes all animals that have a spinal column or vertebral column, which is a key characteristic that distinguishes vertebrates from invertebrates, which lack this structure. Vertebrates encompass a wide range of animals, including mammals, birds, reptiles, amphibians, and fish, all of which share the defining feature of having a backbone that provides structural support and protection for the spinal cord. This backbone is crucial for the complex body structures and functions common in vertebrates, allowing for greater mobility and adaptability in various environments.
