THE NON-CHORDATES

      Non-chordates are animals without a notochord. They are the most abundant and diversified of all animals living or extinct. That makes their study the most fascinating one.

THE CHORDATES       

       Chordates are characterised by a rod-like notochord and a hollow nerve cord on the dorsal side of the gut, and pharynx being perforated with gill slits for respiration. Vertebrates have a vertebral column that replaces the notochord, cephalization of the nervous system, a ventral heart, a post-anal tail and division of the coelom into chambers.
