Vertebrates ( / ˈvɜːrtəbrɪts, - ˌbreɪts /) [3] 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.

Há 4 dias · The defining characteristic of a vertebrate is the vertebral column, formed in the development of the segmented series of vertebrae. In most vertebrates the notochord becomes the nucleus pulposus of the intervertebral discs. However, a few vertebrates, such as the sturgeon and the coelacanth, retain the notochord into adulthood.
Há 1 dia · Bird. Birds are a group of warm-blooded vertebrates constituting the class Aves ( / ˈeɪviːz / ), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
Há 5 dias · The human body is the physical substance of the human organism. Characteristic of the vertebrate form, the human body has an internal skeleton with a backbone, and, as with the mammalian form, it has hair and mammary glands. Learn more about the composition, form, and physical adaptations of the human body.
Há 2 dias · Bird, any of the more than 10,400 living species unique in having feathers, the major characteristic that distinguishes them from other animals. They are warm-blooded vertebrates more related to reptiles than mammals. Learn more about birds in this article.

Há 4 dias · Vertebrate taxonomy is the science of classifying animals with a backbone. By studying the physical characteristics, genetic makeup, and evolutionary relationships of these animals, scientists can classify them into distinct groups and understand their place in the animal kingdom.
