Examples
- There are about 45 . 000 species of chordates , occupying marine , fresh and brackish water and terrestrial habitats
有大约45 . 000种脊索动物，它们占据着海、淡水或淡咸水和陆地的生态环境。 - Amphioxus or lancelet , a cephalochordate , is the extant invertebrate chordate considered to be the closest relationship to the vertebrates
文昌鱼被认为是和脊椎动物亲缘关系最近的动物。 - Chordates are bilaterally symmetrical , triploblastic , segmented coelomates which demonstrate a deuterostomic pattern of early embryonic development
脊索动物两侧对称、三胚层，分节的体腔，在胚胎发育的早期过程中，显示为后口类型。 - The sea urchin represents the first sequenced genome from the echinoderms , which are the closest known relatives of the chordates , the group that includes vertebrates , animals with spinal columns
海胆是首个被排序的棘皮动物，这是与离脊索动物（也包括有脊椎动物）最近的亲属。 - Phylogenetic analysis based on the amino acids of the ubiquitin / ribosomal fused proteins of different animals well reflected the established phylogeny of the chosen organisms , and amphioxus was branched off from chordates and formed a separate cluster with an intermediate placement between invertebrates and vertebrates in the tree
通过对ubiquitin的系统进化分析，发现文昌鱼ubf80除了具有脊椎动物和无脊椎动物的特征外，还具有自己的一些独特的特征，从分子水平上支持了文昌鱼是脊索动物进化过程中的一侧枝的观点。
