Expert Answer
In chordates, a pliable rod called notochord occurs ventral to nerve cord.
In vertebrates, the notochord is replaced by bone or cartilage to form vertebral column.
Chordates include cephalochordates (notochord is present throughout life), urochordates (notochord present only in tail of larve) and vertebrates. So all vertebrates are chordates, but all chordates are not vertebrates. Vertebrates include Pisces, Amphibians, Reptiles, Aves and Mammals.
