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.
There are five main groups of vertebrates: fish, amphibians, reptiles, birds, and mammals. Vertebrates can be either cold-blooded (ectothermic) or warm-blooded (endothermic). They differ in characteristics such as skin covering, reproductive methods, and life cycles.
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 among the most recognizable organisms of the animal kingdom (Figure 1). More than 62,000 vertebrate species have been identified. The vertebrate species now living represent only a small portion of the vertebrates that have existed.
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.
