Idealised vertebrate body plan, showing key characteristics Vertebrates (and other chordates) belong to the Bilateria , a group of animals with mirror symmetrical bodies. [ 6 ] They move, typically by swimming, using muscles along the back, supported by a strong but flexible skeletal structure, the spine or vertebral column . [ 7 ]
The lampreys are a very ancient lineage of vertebrates, though their exact relationship to hagfishes and jawed vertebrates is still a matter of dispute. [7] Molecular analysis since 1992 has suggested that hagfish are most closely related to lampreys, [8] and so also are vertebrates in a monophyletic sense. Others consider them a sister group ...
The following is a list of the classes in each phylum of the kingdom Animalia.There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla.
The general characteristics of the third through sixth cervical vertebrae are described here. The first, second, and seventh vertebrae are extraordinary, and are detailed later. The bodies of these four vertebrae are small, and broader from side to side than from front to back.
For a fuller treatment of this taxonomy, see the vertebrate article. The position of hagfish in the phylum Chordata is not settled. Phylogenetic research in 1998 and 1999 supported the idea that the hagfish and the lampreys form a natural group, the Cyclostomata, that is a sister group of the Gnathostomata. [3] [4]

Cladistics is a method of classification of life forms according to the proportion of characteristics that they have in common (called synapomorphies). It is assumed that the higher the proportion of characteristics that two organisms share, the more recently they both came from a common ancestor.
