Vertebrata
Also known as animals with backbone, subphylum vertebrate, vertibrate, vertebrates, subphylum Vertebrata, vertebrate
Vertebrates (), 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.
AI overview
Vertebrates are animals that have a backbone (vertebral column) and a skull (cranium), which protect their spinal cord and brain respectively. This group includes familiar animals like fish, amphibians, reptiles, birds, and mammals, making vertebrates one of the most recognizable and studied categories of animals.

脊椎动物亚门是脊索动物门下的一个亚门。拉丁文学名是Vertebrata，词根是“vertebra”，意为脊椎骨。目前所知最早的脊椎動物是中國雲南省昆明發現的豐嬌昆明魚，距今約5.3億年前。 和節肢動物殼長在體外或軟體動物無骨骼不同，脊椎动物亚门的动物的脊椎都包在骨头里面，是脊索动物门中最大和最先进的亚门。这个亚门的成员拥有的肌肉大多数是一对一对的肌肉。神经系统有一部分在脊梁骨中间。循环系统较完善，有心脏可以促进血液循环。脂肪組織是絕大多數脊椎動物特有的構造，可以使之一段時間不進食，而不會能量耗竭而死。 脊椎动物亚门动物的脊椎是体内骨，有软骨也有硬骨。在动物成长时，这个骨架支持体型。因此脊椎动物可以比无脊动物长得大，而且平均体量也比较大。

Vertebrates (), 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.
The vertebrates make up the subphylum Vertebrata ( ) with some 65,000 species, by far the largest ranked grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata. The jawed fish include both the cartilaginous fish and the bony fish. Bony fish include the lobe-finned fish, which gave rise to the tetrapods, the animals with four limbs. Despite their success, vertebrates still only make up less than five percent of all described animal species.
