The vertebrates consist of all the taxa within the subphylum Vertebrata (/ ˌ v ɜːr t ə ˈ b r eɪ t ə /) (chordates with backbones) and represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise groups such as the following infraphyla and classes: Agnatha or jawless fish ...
5 days ago · Vertebrate, any animal of the subphylum Vertebrata. They have backbones and are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone. Its members include fishes, amphibians, reptiles, birds, and mammals.
Vertebrates are deuterostomal animals with bony or cartilaginous axial endoskeleton — known as the vertebral column, spine or backbone — around and along the spinal cord, including all fish, amphibians, reptiles, birds and mammals. The vertebrates consist of all the taxa within the subphylum Vertebrata and represent the overwhelming majority of the phylum Chordata, with currently about ...
- Class Mammalia. All mammals have hair, three ear bones, and mammary glands. These are the distinguishing and unique features of class Mammalia. Less unique characteristics within the larger scope of subphylum Vertebrata include giving birth to live young (livebearers), warm blood (endothermic), a heart comprised of four chambers, internal fertilization, and a high level of parental care.
- Class Aves. Class Aves is a group of warm-blooded animals with high body temperatures of approximately 106°F (41.1°C). Other specific features are body shape and divisions into head, neck, trunk, and tail.
- Class Reptilia. Reptiles are cold-blooded vertebrates with scales or scutes. As with birds, they have a single occipital condyle which allows them to rotate the head further than mammals.
- Class Amphibia. Vertebrate amphibians can live in water or on land, although they are only found in freshwater. The word amphibian means ‘two lives’. Class Amphibia is a group of cold-blooded, egg-laying animals with or without limbs, eyelids, tails, gills, scales, and/or neck.
Vertebra. A section of the human vertebral column, showing multiple vertebrae in a left posterolateral view. Each vertebra ( pl.: vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to ...
vertebrate, Any animal of the chordate subphylum Vertebrata, which includes the fishes, amphibians, reptiles, birds, and mammals. Vertebrates have an internal skeleton formed of cartilage, bone, or both. The skeleton consists of a backbone (vertebral column), which partly encloses a spinal cord; a skull, which encloses the brain; and usually ...
