Question

Among the members of the animal kingdom, about 95% do not posses a backbone (vertebral column)
and hence are described as invertebrates. The remaining animals represent a group called chordates
which posses a solid supporting structure on the dorsal side of the body called notochord, at some stage
of their life cycle. Among chordates, the major group is that or vertebrates in which the notochond is
replaced in the adult stage by a vertebral column.
At present, there are 33 distinct groups or phyla of invertebrates and distinct groups or phyla of
chordates have been identified. However, as new groups are being continuously discovered the
classification of animals is general and invertebrates in particular, is being constantly revised. However,
one can recongnise nine major phyla. Since they constitute nearly 90% of the known invertebrates, all
the chordates are placed in one major phylum. 1) what is the name given to animals which possess backbones​

Answer 1

Answer:

Vertrbrates or Craniates
