Vertebrates (/ ˈvɜːrtəbrɪt, - ˌbreɪt /), [3] also called craniates, are animals with a vertebral column and a cranium. The vertebral column surrounds and protects the spinal cord, while the cranium protects the brain.
Thus, vertebrates refer to animals with a characteristic bony or cartilaginous axial endoskeleton known as the vertebral column, spine, or backbone. Fish, amphibians, reptiles, birds, and mammals are all examples of vertebrates.
Vertebrates are animals with a backbone, or vertebral column, that protects a central nerve cord running along the body. They include fish, amphibians, reptiles, birds, and mammals. Despite being the animals most familiar to us, vertebrates make up a small fraction of all animal species on Earth.
Vertebrates are a diverse group of animals found across nearly every environment on Earth, from fish in oceans to birds soaring above and mammals, including humans, on land.
Vertebrates are a diverse group of animals characterized by having backbones, internal skeletons, well-developed brains, and bilateral symmetry. They belong to the phylum Chordata and evolved from ancient chordates.
Vertebrates, which include fishes, reptiles, amphibians, birds, and mammals, all share a vertebral column, or a chain of bony elements (vertebrae) that run along the dorsal surface from head to tail and form the main skeletal axis of the body.
