${\huge{\pink{\underbrace{\overbrace{\mathbb{\blue{ANSWER:-}}}}}}}$

Vertebrates:-

Vertebrates are advanced chordates. Notochord is present only in  the embryonic stages and it is replaced by a cartilagenous/bony vertebral column in the adult forms, while dorsal nerve cord is transformed into brain and spinal cord. Vertebral column and endoskeletal allow to have a completely  different distribution of muscle attachement points to be used for movement. Vertebrates are bilateral symmetrical, triploblastic, segmented, have paired gill pouches and a true coelom. There is complex differentiation of body tissues and organs.

Vertebrates are of 6 types:

(i) Cyclostomata

(ii) Pisces

(iii) Amphibia

(iv) Reptilia

(v) Aves

(vi) Mammalia
