What is Noto chord?
In anatomy, the notochord is a flexible rod formed of a material similar to cartilage . If a species has a notochord at any stage of its life cycle, it is, by definition, a chordate. ... In Tunicates the notochord is present only in the larval stage, being completely absent in the adult animal.

What is difference between chordates and non Chordata?
The major point to differentiate between chordates and non-chordates is that chordates have a spinal cord or backbone in their body structure whereas non-chordates are without backbone or notochord in their body structure.
What is the difference between chordates and vertebrates?
Chordates are characterized by the presence of a notochord. ... The main difference between chordates and vertebrates is that some chordates do not have a vertebral column whereas all vertebrates have a vertebral column . In vertebrates, the vertebral column surrounds and protects the nerve cord.
