"Vertebrata" Natural Recordings by Native Speakers
Vertebrata refers to a subphylum of chordate animals that are characterized by the presence of a backbone (vertebral column) or spinal column. This group includes all fishes, amphibians, reptiles, birds, and mammals. The term "vertebrata" is derived from the Latin word for "back" or "spine" (vertebra), indicating the prominent structure common to all these animals. Vertebrates have a head, a spinal cord, a set of paired limbs (or flippers in aquatic species), and often, a highly developed brain. The vertebral column serves as a protective enclosure for the spinal cord and offers support and flexibility to the torso.
