​

Answer 1

Explanation:

Only chordates with a vertebral column are vertebrates while protochordates lack a vertebral column. This is one main main difference between chordates and protochordates.

The main difference between chordates and protochordates is that the chordates are the animals that have distinct characteristics such as a notochord, dorsal nerve chord, pharyngeal slits, and a muscular tail whereas the protochordates are an informal group of invertebrates within chordates. Furthermore, the three subphyla of chordates are Vertebrata, Urochordata, and Cephalochordata while protochordates consist of both Urochordata and Cephalochordata.

Chordates and protochordates represent animals with a higher organization within the kingdom Animalia.
