Chordates are animals characterized by the presence of notochord at some stage during their development. Members possess a hollow nerve cord and pharyngeal gill slits. The other general characteristic features of Chordates are as follows:
- They are bilaterally symmetrical, triploblastic, and coelomate with the organ-system level of organization.
- They hold a post-**** tail
- The body includes a closed circulatory system.
- In some members of Phylum Chordata, the notochord is present only in the larval tail, and in some, it is present throughout their life from head to tail region.
- Chordates have many sub-divisions and Protochordates are one of the earliest to evolve.
Examples of this phylum include Ascidia, Salpa, Doliolum, Amphioxus or Lancelet.
