What is the phylum chordata?

Answer 1

Chordata is the phylum of animals that have a number of features in common, but most notably a notochord (which is called a spinal cord in humans because we have a backbone, a spine, through which it is routed). All the vertebrates (animals with a backbone) are grouped within this phylum. The chordates also include a number of other animals that do not have a backbone, but do have the notochord.

Answer 2

The phylum Chordata is a taxonomic group. All animals which have a spine, or backbone, are classified in the phylum Chordata. There are three subphylums in Chordata: Urochordata (tunicates), Cephalachordata (lancelets), and Vertebrata (vertebrates). This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body.

Answer 3

Phylum Chordata is a group of animals characterized by the presence of a notochord, a hollow nerve cord, pharyngeal slits, and a post-anal tail at some stage in their life cycle. This phylum includes vertebrates and a few closely related invertebrates.
